Ceremony marks the first stage of the Sirius project

New Synchrotron Light Source is the largest and most complex research structure ever built in Brazil

The Brazilian President, Michel Temer, and the Minister of Science, Technology, Innovation and Communications, Gilberto Kassab, participated on Wednesday 14th November in the ceremony commemorating the first stage of the new Brazilian Synchrotron Light Source, Sirius, in the Brazilian Center for Research in Energy and Materials (CNPEM), in Campinas (SP). Started in 2012, Sirius is the largest project in Brazilian science, a state-of-the-art research infrastructure, strategic for cutting-edge scientific research and for finding solutions to global problems in areas such as health, agriculture, energy and the environment.

This first stage includes the conclusion of the construction works of the building that houses the entire research infrastructure, in addition to the assembly of the Linear and Booster Accelerators. The Storage Ring is currently being assembled.
The delivery of the next stage of the project, scheduled for the second half of 2019, includes the start of the Sirius operation and the opening of the first six beamlines for researchers. The complete project includes seven other beamlines, expected to be opened in 2021. However, the number of beamlines can be gradually expanded, reaching up to 40 experimental stations.

50 years later, Wilson Lab stays cutting edge

October 2018 marks the 50th anniversary of the dedication of the Wilson Synchrotron Laboratory.

Initially built for $11million and promising to deliver cutting-edge research in elementary particle physics, it was the NSF’s largest project at that time. Fifty years later, the lab is going through its biggest upgrade in decades.
Chris Conolly looks at the concrete floor of Wilson Lab, eyeing up the numerous holes drilled by one of the contractors for the upgrade project. These one-inch holes pockmark the 10,000sf experimental hall of the Wilson Synchrotron Laboratory. In a way, these holes represent the numerous experiments conducted over the past 50 years.

There are a lot of holes. 652 to be exact, as the CHESS X-ray Technical Director and CHESS-U beamline project manager easily points out.
“It’s almost like being an archaeologist”, says Conolly, as he walks through the maze of newly constructed hutches in the experimental hall. He stops near the sector II hutches, “especially this spot here,” he says, presenting a repeating pattern of drilled holes arcing across the floor. The pattern spans a total of about 25 feet, and Chris, who has been with CHESS for the past 18 years, has no idea what was held down by the bolts marked in the floor.

2018 ALS User Meeting Highlights

Past, present, and future converged at the ALS User Meeting, held October 2–4, 2018. About 480 registrants helped celebrate the 25th anniversary of first light at the ALS and the announcement of CD-1 approval for the ALS Upgrade project (ALS-U), a major federal milestone. Users’ Executive Committee (UEC) Chair Will Chueh kicked things off by acknowledging the organizers—UEC members Jennifer Ciezak-Jenkins, Alex Frañó, and Michael Jacobs—and thanking the ALS for its support. He also explained the organizing principle behind the program: to engage student and young-scientist users and strengthen interactions between users in general. Jeff Neaton, Berkeley Lab’s Associate Laboratory Director for Energy Sciences, then extended an official welcome to attendees. He noted that it’s been an exciting year for the ALS, which gained a new director, Steve Kevan, in addition to CD-1 approval for ALS-U.

New NSLS-II beamline illuminates electronic structures

MIT scientists conduct the first experiment at NSLS-II’s Soft Inelastic X-ray Scattering beamline.

On July 15, 2018, the Soft Inelastic X-ray Scattering (SIX) beamline at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science User Facility at DOE’s Brookhaven National Laboratory—welcomed its first visiting researchers. SIX is an experimental station designed to measure the electronic properties of solid materials using ultrabright x-rays. The materials can be as small as a few microns—one millionth of a meter.
The first researchers to take advantage of the world-class capabilities at SIX were Jonathan Pelliciari and Zhihai Zhu, two scientists from the Massachusetts Institute of Technology (MIT). The pair used SIX to study a chromate sample, a fascinating material with novel applications in magnetism, batteries, and catalysis. Little was known about the electronic structure of the chromate sample the MIT team studied at SIX, and their research is aimed at unlocking the properties of this material. To do so, they needed the atomic sensitivity and energy resolution of the SIX beamline.

Advanced Light Source upgrade project moves forward

An upgrade of Berkeley Lab’s X-ray facility clears next stage in federal approval process.

The Advanced Light Source (ALS), a scientific user facility at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab), has received federal approval to proceed with preliminary design, planning and R&D work for a major upgrade project that will boost the brightness of its X-ray beams at least a hundredfold.

The upgrade will give the ALS, which this year celebrates its 25th anniversary, brighter beams with a more ordered structure – like evenly spaced ripples in a pond – that will better reveal nanoscale details in complex chemical reactions and in new materials, expanding the envelope for scientific exploration.
“This upgrade will make it possible for Berkeley Lab to be the leader in soft X-ray research for another 25 years, and for the ALS to remain at the center of this Laboratory for that time,” said Berkeley Lab Director Mike Witherell.

Steve Kevan, ALS Director, added, “The upgrade will transform the ALS. It will expand our scientific frontiers, enabling studies of materials and phenomena that are at the edge of our understanding today. And it will renew the ALS’s innovative spirit, attracting the best researchers from around the world to our facility to conduct their experiments in collaboration with our scientists.”

Spectacular transport: Undulator moved to the electron storage ring BESSY II

A worldwide unique undulator developed at Helmholtz-Zentrum Berlin (HZB) was installed in the storage ring BESSY II on September 20, 2018.

It supplies the “Energy Materials In-Situ Lab EMIL” with the hard X-ray light from BESSY II. The transport of the six-ton device was spectacular: several cranes were used to transport the undulator just a few hundred meters from the production building to the storage ring.

Undulators are key components to operate electron storage rings. The electrons pass through complex magnetic structures and are forced into an undulating orbit. This generates synchrotron radiation of great brilliance. What is special about the new undulator is that the magnetic structures are located in a vacuum chamber and cooled with liquid nitrogen. This permits significantly stronger magnetic fields to be generated to deflect the electrons.

New hutches installed as CHESS-U takes shape

The construction portion of the CHESS-U upgrade is nearing completion as teams work to assemble the last of the experimental hutches. While there is still plenty of work to be done, the preparation for becoming a true 3rd-generation lightsource is paying off.

In early 2019, CHESS-U will have an increased energy of the electron beam, from 5.3 to 6.0 GeV, double the current from 100 to 200 mA, and reduction of the horizontal emittance of the x-ray beam from 100nm to 30nm.
While these high energy x-rays will soon benefit researchers from around the world, new hutches are currently being built to contain and control the beam from the new undulator sources being installed. These hutches, or light-tight experimental rooms, will contain the x-rays by using multiple layers of lead for the walls and ceilings with additional shielding at the seams.

The design and installation of these hutches has been carefully coordinated. As utilities, cables and HVAC systems start to enter each room, it is worth noting the clever design that was used in order to retain the radiation-tight rooms. While safety was definitely at the forefront of the engineers’ minds, the ability to streamline the installation process was deliberately considered, and has since proven useful to compensate for any unavoidable delays.

New cryo-EM Collaboration

UK set to be global leader in providing large-scale industrial access to Cryo-EM for drug discovery thanks to new collaboration.


Thermo Fisher Scientific and Diamond Light Source are creating a step change for life sciences sector, a one-stop shop for structural biology and one of largest cryo-EM sites in the world.
An agreement to launch a new cryo-EM capability for use in the life sciences industry sector by Thermo Fisher Scientific, one of the world leaders in high-end scientific instrumentation, and Diamond Light Source, the UK’s national synchrotron and one of the most advanced scientific facilities in the world, was announced today ahead of the official opening of the new national electron bio-imaging centre (eBIC) which will be held at Diamond on September 12th 2018.

This announcement confirms Diamond as one of the major global cryo-EM sites embedded with an abundance of complementary synchrotron-based techniques, and thereby, provides the life sciences sector with an offer not available anywhere else in the world.

Professor Dave Stuart, Life Sciences Director at Diamond and MRC Professor of Structural Biology at the University of Oxford, Department of Clinical Medicine, says, “Access to 21st century scientific tools to push the boundaries of scientific research is essential for both academia and industry, and what we have created here at Diamond is truly unique in the world in terms of size and scale. The new centre offers the opportunity for almost real-time physiology, capturing proteins in action at cryo-temperatures by flash-freezing them at various stages. What Diamond has created with eBIC is an integrated facility for structural biology, which will accelerate R&D for both industry and academic users. The additional advanced instruments made available by Thermo Fisher will position the UK as a global leader in providing large-scale industrial access to cryo-EM for drug discovery research. Our new collaboration provides a step change in our offer for industry users and helps ensure that R&D remains in the UK.”

Shutdown BESSY II: work has started

As of 30 July 2018, BESSY II will be down for several weeks.

In the summer shutdown, important components in the storage ring tunnel will be replaced and overhauled. The first conversion work for the BESSY VSR project also begins.  Upgrading BESSY II into a variable-pulse-length storage ring (BESSY-VSR) will provide unique experimental conditions for researchers worldwide. The shutdown lasts until 30 September 2018, and user operation will recommence on 30 October 2018.

While the ring is down, the HZB employees will be completely modifying the multipole wavelength shifter, the EDDI beamline and the radiation protection hutches. This space will be needed for installing the cold supply for the superconducting cavities in the storage ring. These are key components in the creation of BESSY VSR. Keeping them cold, however, requires an elaborate infrastructure, which is to be built up in the experimental hall over the next two years.

Young talent from LNLS awarded at international conference

Work on components for Sirius was elected best poster.

Gabriel Vinícius Claudiano, member of the Brazilian Synchrotron Light Laboratory (LNLS), was awarded the prize for best poster in the category “young engineer under 30” during the tenth edition of the MEDSI (Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation) conference, which was held in Paris, France, between June 25th and 29th.

Gabriel’s work is related to the development of components for the beamlines of the new Brazilian synchrotron light source, Sirius. These components are located at the interface between the storage ring and the beamlines, which is called front-end, and their function is to absorb part of the synchrotron light beam to protect sensitive equipment.

Third light source generates first X-ray light

European XFEL starts operation of its third light source, exactly a year after the first X-ray light was generated in the European XFEL tunnels. The third light source will provide light for the MID (Materials Imaging and Dynamics) and HED (High Energy Density Science) instruments scheduled to start user operation in 2019. All three light sources, successfully run in parallel for the first time on the anniversary of European XFEL’s first light, will eventually provide X-rays for at least six instruments. At any one time, three of these six instruments can simultaneously receive X-ray beam for experiments. “The operation of the third light source, and the generation of light from all sources in parallel, are important steps towards our goal of achieving user operation on all six instruments” said European XFEL Managing Director Robert Feidenhans’l. “I congratulate and thank all those involved in this significant accomplishment. It was a tremendous achievement to get all three light sources to generate light within the space of one year.”

To generate flashes of X-ray light, electrons are first accelerated to near the speed of light before they are moved through long rows of magnets called undulators. The alternating magnetic fields of these magnets force the electrons on a slalom course, causing the electrons to emit light at each turn. Over the length of the undulator, the produced light interacts back on the electron bunch, thereby producing a particularly intense light. This light accumulates into intensive X-ray flashes. This process is known as ‘self-amplified spontaneous emission’, or SASE. European XFEL has three SASE light sources. The first one, SASE 1, taken into operation at the beginning of May 2017, provides intense X-ray light to the instruments SPB/SFX (Single Particles, Clusters and Biomolecules and Serial Femtosecond Crystallography) and FXE (Femtosecond X-ray Experiments), the first instruments available for experiments and operational since September 2017. The second light source, SASE 3, was successfully taken into operation in February 2018 and will provide light for the instruments SQS (Small Quantum Systems) and SCS (Spectroscopy and Coherent Scattering), scheduled to start user operation in November 2018. SASE 1 and SASE 3 can be run simultaneously – high speed electrons first generate X-ray light in SASE 1, before being used a second time to produce X-ray light of a longer wavelength in SASE 3. Now, exactly a year after the first laser light was generated in the European XFEL tunnels, the third light source, SASE 2, is operational. SASE 2 will generate X-ray light for the MID (Materials Imaging and Dynamics) and HED (High Energy Density Science) instruments scheduled to start user operation in 2019. The MID instrument will be used to, for example, understand how glass forms on an atomic level, and for the study of cells and viruses with a range of imaging techniques. The HED instrument will enable the investigation of matter under extreme conditions such as that inside exoplanets, and to investigate how solids react in high magnetic fields.

Support for HZB’s future and call for rapid planning of Bessy III

The Helmholtz-Zentrum Berlin (HZB) has received an evaluation of “excellent” in a review of science programmes undertaken at all Helmholtz Research Centres.

This provides the foundation for future financing of HZB.
Two committees of leading international scientists visited the HZB for a week each at the beginning of this year. They evaluated the HZB’s contributions to the Helmholtz programmes in the research areas of “Matter” and “Energy”. Now the written evaluations are available. The team spirit of all employees involved in the HZB was particularly emphasised.

The report states that the HZB and the Helmholtz Association have made decisions characterised by vision. The right course had been set both in terms of infrastructure and in recruiting people. The HZB can rely on highly competent, committed employees at all levels.

All research programmes of the HZB have received an evaluation of “excellent”. The HZB contributions to the MML programme (From Matter to Materials and Life) focussing on the use of photons are considered to be leading, with all of its participating groups receiving the top marks of “Outstanding” or “Excellent”. The Renewable Energies (RE) and the Future Information Technologies (FIT) programmes, the instrumentation at the BESSY II synchrotron (some of which is unique), and the BER II research reactor were likewise evaluated highly.

Sending electrons on a rollercoaster ride

A first-of-its-kind x-ray instrument for frontier research with high-brightness x-rays is now in operation at Argonne National Laboratory. The new device utilizes a unique superconducting technology that speeds electrons on a path much like that of a rollercoaster.

The insertion device (ID), called a Helical Superconducting Undulator (HSCU), was designed at the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at DOE’s Argonne National Laboratory. The device has three primary advantages over other types of IDs for producing high-brightness x-rays: (1) it generates a stronger magnetic field than other IDs; (2) it allows researchers to select a single energy from the x-ray beam without using any x-ray optics; and (3) it produces an x-ray beam with circular polarization. Argonne developed the helical undulator with $2 million in funding from the DOE Office of Science.

NEXT project receives secretary’s achievement award

On Wednesday, Mar. 14, Under Secretary of Energy Mark Menezes presented the Secretary’s Achievement Award—a U.S. Department of Energy (DOE) Office of Project Management (PM) Award—to the National Synchrotron Light Source II (NSLS-II) Experimental Tools (NEXT) project management team for completing the project on schedule and under budget, and for delivering scientific instruments to NSLS-II that will benefit research for years to come.

The NEXT project team coordinated the development and construction of five new beamlines (experimental stations) at NSLS-II, a highly advanced synchrotron light source and a DOE Office of Science User Facility located at DOE’s Brookhaven National Laboratory. Scientists use NSLS-II’s ultra-bright light to study materials with nanoscale resolution and exquisite sensitivity. The five new beamlines developed through NEXT complement the existing beamline portfolio at NSLS-II, and offer new, unique, and cutting-edge scientific capabilities.

“These state-of-the-art beamlines support the DOE Office of Science mission to deliver scientific discoveries and major scientific tools to transform our understanding of nature and to advance the energy, economic, and national security of the United States,” said Robert Caradonna, DOE Brookhaven Site Office Federal Project Director. “This award reflects the drive and dedication of the NEXT project team that made this endeavor a huge success. It was an honor to work with such talented people on such an important a project.”

COSMIC impact: next-gen X-ray microscopy platform now operational

A next-generation X-ray beamline now operating at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) brings together a unique set of capabilities to measure the properties of materials at the nanoscale.

Called COSMIC, for Coherent Scattering and Microscopy, this X-ray beamline at Berkeley Lab’s Berkeley Lab’s Advanced Light Source (ALS) allows scientists to probe working batteries and other active chemical reactions, and to reveal new details about magnetism and correlated electronic materials.
COSMIC has two branches that focus on different types of X-ray experiments: one for X-ray imaging experiments and one for scattering experiments. In both cases, X-rays interact with a sample and are measured in a way that provides, structural, chemical, electronic, or magnetic information about samples.

The beamline is also intended as an important technological bridge toward the planned ALS upgrade, dubbed ALS-U, that would maximize its capabilities.

Twin Orbit operation successfully tested at BESSY II

The first “Twin Orbit User Test week” at BESSY II in February 2018 was a big success and can be considered as an important step towards real user operation.

Physicists at Helmholtz-Zentrum Berlin have been able to store two separate electron beams in one storage ring. The twin orbit operation mode can serve users with different needs of the time structure of the photon pulses simultaneously and offers elegant options regarding the future project BESSY VSR.

The Twin Orbit operation mode makes use of non-linear beam dynamics and provides two stable well separated orbits for storing two electron beams in one storage ring. The bunch fill patterns of both orbits can be chosen, to some extent, independently, which allows for fulfilling normally incompatible user needs, simultaneously. For example, one orbit can be used to store a homogenous multi bunch fill to deliver high average brilliance for photon hungry experiments, whereas only one single bunch is stored on the other orbit for timing experiments, providing a much lower pulse repetition rate.
