The ALBA Synchrotron to become a 4th generation facility

The Rector Council of the ALBA Synchrotron, counting with the participation of the Ministry of Science and Innovation and the Department of Business and Knowledge of the Generalitat de Cataluña, chaired by Minister Pedro Duque, has given the green light to start working in 2021 on the ALBA II project, an ambitious program that will transform ALBA into a 4th generation synchrotron facility upgrading the accelerator and other components and building new beamlines.

Nowadays, synchrotron facilities are experiencing an outstanding technological evolution, applying new solutions for the design and construction of accelerators, the development of X-ray detectors and the management of experimental data.

The so-called 4th generation synchrotron facilities, compared to those of the 3rd generation, produce a brighter and more coherent photon beam. When analyzing matter, they provide inaccessible capabilities as of today, in terms of resolution, detection levels and the understanding of chemical and electromagnetic properties. In addition, they offer new technological approaches to solve society’s challenges more efficiently and move towards a sustainable and smart economy in a more efficient health system.

Milestone in ALS-Upgrade project will bring in a new ring

Construction of innovative accumulator ring as part of ALS-U project will keep Berkeley Lab at the forefront of synchrotron light source science.

An upgrade of the Advanced Light Source (ALS) at the U.S. Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab) has passed an important milestone that will help to maintain the ALS’ world-leading capabilities.

On Dec. 23 the DOE granted approval for a key funding step that will allow the project to start construction on a new inner electron storage ring. Known as an accumulator ring, this inner ring will feed the upgraded facility’s main light-producing storage ring, and is a part of the upgrade project (ALS-U).

This latest approval, known as CD-3a, authorizes an important release of funds that will be used to purchase equipment and formally approves the start of construction on the accumulator ring.

Sirius reaches his first stored electron beam

The new Brazilian synchrotron light source continues its successful commissioning

On Saturday, December 14th, CNPEM’s team stored electrons in Sirius’s storage ring for several hours. This is a prerequisite for producing synchrotron light, and it happens only a few weeks after the first electron loop around the main accelerator was achieved.
In addition, on Monday, December 16th, with the connection of the accelerator to one of the beamlines set up for testing, it was possible to receive the first X-ray pulse, still discrete due to the small number of circulating electrons.
The achievement came after an intense and thorough work of adjusting hundreds of equipment parameters, another very important milestone in the Sirius commissioning process. The team is now dedicated to achieving higher and higher currents needed to produce synchrotron light of enough intensity for the first scientific experiments.
Sirius is the largest and most complex scientific infrastructure ever built in Brazil and one of the first 4th generation synchrotron light source to be built in the world and it was designed to put Brazil at the forefront of this type of technology.

First stored beam

6 December, 12.30 pm. Today, the electrons have been stored for the first time, in the new Extremely Brilliant Source (EBS) storage ring.

Today, 6 December 12:30 pm was a great and intense moment for all the ESRF teams: the electrons have been stored for the first time in the new EBS storage ring, only five days after the start of the EBS storage ring commissioning. This is a new key milestone on the way to opening to the international scientific community the first high-energy fourth-generation synchrotron light source, known as EBS – Extremely Brilliant Source.

” Seeing the first beam stored only five days after the start of the commissioning is a huge achievement and an intense moment for all involved. EBS is becoming a reality.” said Pantaleo Raimondi, ESRF accelerator and source director and EBS storage ring concept inventor and project leader.

More magnets, smoother curves: the Swiss Light Source upgrade

The Swiss Light Source SLS is set to undergo an upgrade in the coming years: SLS 2.0.

The renovation is made possible by the latest technologies and will create a large-scale research facility that will meet the needs of researchers for decades to come.

Since 2001, “the UFO” has been providing reliable and excellent service: In the circular building of the Swiss Light Source SLS, researchers from PSI and all over the world carry out cutting-edge research. For example, they can investigate the electronic properties of novel materials, determine the structure of medically relevant proteins, and make visible the nanostructure of a human bone.
“Internationally, the SLS has been setting standards for nearly two decades”, says Terence Garvey, SLS 2.0 accelerator project head. Now, Garvey continues, it’s time for a modernisation. In the coming years, SLS is expected to undergo an upgrade with the project title SLS 2.0. SLS will remain within the same UFO-shaped building, but will get changes in crucial areas inside. Garvey is one of the two project leaders for the upgrade, together with Philip Willmott.

First electrons turn in the ESRF’s Extremely Brilliant Source Storage Ring

This is an important milestone on the way to opening to the international scientific community the first high-energy fourth-generation synchrotron light source, known as EBS – Extremely Brilliant Source.

It marks the successful completion of the engineering and installation of a worldwide-unique accelerator within the existing ESRF infrastructure, and the start of the commissioning phase of a brand-new generation of high-energy synchrotron.
Expectation was high in the ESRF’s control room on 2 December as teams carefully monitored the first turns of the electrons around the new EBS storage ring. “Seeing the first electrons circulating is a huge achievement and proof of the hard work and expertise of the teams who have been working on this since 2015,” said Pantaleo Raimondi, ESRF accelerator and source director and EBS storage ring concept inventor and project leader. “It’s a great moment for all involved.”

One of Sirius’ most important steps: first electron loop around the storage ring

This is one of the most important stages of the largest scientific project in Brazil .

The Sirius project has just completed one of its most important steps: the first electron loop around its main particle accelerator, called the Storage Ring. In this large structure, 518 meters in circumference, the electrons accelerated to very high energies produce synchrotron light: a very bright light used in scientific experiments that could revolutionize knowledge in health, energy, materials and more.
The first loop demonstrates that thousands of components such as magnets, ultra-high-vacuum chambers and sensors are working in sync, and that the entire structure, with parts weighing hundreds of kilograms, have been aligned to micrometer standards (up to five times smaller than a strand of hair) needed to guide the trajectory of the particles.
Sirius is the largest and most complex scientific infrastructure ever built in Brazil and one of the first 4th generation synchrotron light source to be built in the world and it was designed to put Brazil at the forefront of this type of technology.

The next steps of the project include concluding the assembly of the first beamlines: the research stations where scientists conduct their experiments. These stations allow researchers to study the structure of virtually any organic and inorganic materials, such as proteins, viruses, rocks, plants, soil, alloys, among many others, in the atomic and molecular scale with very high resolution and speed.

Welcome back users!

This month marks the official start of user operation at CHESS and all three partner programs: The NSF funded CHEXS, as well as MacCHESS supported by NIH and NYSTAR, and the Materials Solutions Network at CHESS, or MSN-C, funded by the Air Force Research Lab (AFRL), all welcomed users to new hutches and beamlines. 

Louise Debefve stands outside a hutch on the experimental floor of the Cornell High Energy Synchrotron Source, CHESS. She is preparing the experimental equipment for some of the first data to be collected at CHESS since the completion of the CHESS-U upgrade. The platinum samples that she is about to study at the new beamlines will provide insights into the catalytic function of the element, enabling for example the generation of cleaner energy powering everything from cars to laptops.

But for now, Louise is happy to just be using the X-rays again, a familiar occurrence for the former graduate student, who spent years developing her research of catalysts through the use of X-rays at SSRL. As a postdoc at CHESS, Louise initially found herself right in the middle of the feverish construction of the upgrade, with no X-rays available for research.

The driving force behind Cornell Compact Undulators at CHESS

Researchers at CHESS are working to further improve the already impressive CHESS Compact Undulator, or CCU.

Within the new NSF-funded CHEXS award, Sasha Temnykh is developing a new driving mechanisms that will add variable gap control and even better tuning of the device, both desirable qualities for a variety of experimental needs.

Undulators are critical devices for the creation of brilliant X-rays at CHESS and other lightsources around the world. With the recent CHESS-U upgrade, the Cornell Electron Storage Ring, CESR, is now outfitted with seven new insertion devices. As the beam circulates around CESR, it passes through a series of alternating magnets in the undulators, resulting in X-rays that are roughly 20 times brighter than those produced prior to the upgrade, making CHESS an even more powerful X-ray source.

Researchers at CHESS lead by Sasha Temnykh are working continuously to improve the already impressive CHESS Compact Undulator, or CCU. The CCUs are about ten times more compact, lighter, and less expensive compared to conventional insertion devices typically used at other lightsource. They also require a significant shorter fabrication time. Nine CCUs have already been constructed in industry from the Cornell-held patent, and according to KYMA, the manufacturer of the CCU, other labs are starting to show interest in the device.

Particle accelerators drive decades of discoveries at Berkeley Lab and beyond

Berkeley Lab’s expertise in accelerator technologies has spiraled out from Ernest Lawrence’s earliest cyclotron to advanced compact accelerators.

Accelerators have been at the heart of the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) since its inception in 1931, and are still a driving force in the Laboratory’s mission and its R&D program. Ernest O. Lawrence’s invention of the cyclotron, the first circular particle accelerator – and the development of progressively larger versions – led him to build on the hillside overlooking the UC Berkeley campus that is now Berkeley Lab’s home. A variety of large cyclotrons are in use today around the world, and new accelerator technologies continue to drive progress.
“Our work in accelerators and related technologies has shaped the growth and diversification of Berkeley Lab over its long history, and remains a vital core competency today,” said James Symons, associate laboratory director for Berkeley Lab’s Physical Sciences Area.

Advanced Photon Source upgrade

The U.S. Department of Energy (DOE) Office of Science (SC) has given DOE’s Argonne National Laboratory approval in the next phase of the $815M upgrade of the Advanced Photon Source (APS), a premier national research facility that equips scientists for discoveries that impact our technologies, economy, and national security.
DOE’s Critical Decision 3 (CD-3) milestone approval is a significant recognition of DOE’s acceptance of Argonne’s final design report for the complex APS Upgrade (APS-U), and authorizes the laboratory to proceed with procurements needed to build the nation’s brightest energy, storage-ring based X-ray source. The upgrade positions the APS to be a global leader among the new generation of storage-ring light sources that is now emerging.
Argonne’s APS, which works like a giant X-ray microscope, is a DOE Office of Science User Facility supported by the Scientific User Facilities Division of the Basic Energy Sciences Program in the Office of Science. It produces extremely bright, focused X-rays that peer through dense materials and illuminate the structure and chemistry of matter at the molecular and atomic level. By way of comparison, the X-rays produced at today’s APS are up to one billion times brighter than the X-rays produced in a typical dentist office.

Project Director Dave Robin announces ALS-U project beamlines

Over the past year, a process involving ALS and ALS-U staff, the ALS user community, and external advisory committees has been ongoing to select the insertion-device beamlines that will be built and upgraded within the scope of the ALS-U Project. These beamlines will join existing ALS beamlines to form the full complement of capabilities that will be available at the upgraded ALS in several years. I am delighted to inform you that the selection process is now complete and to announce the result.

The ALS-U Project will build two new beamlines

  • a soft x-ray beamline in Sector 10, dubbed “FLEXON,” whose high-brightness coherent flux and multiple complementary techniques will probe the roles of multiscale heterogeneity in quantum materials; and
  • a tender x-ray beamline in Sector 8, whose coherent scattering and scanning spectromicroscopy capabilities will address challenges at the frontiers of diverse scientific areas, ranging from soft condensed matter and biomaterials to energy science and Earth and environmental sciences.

Conclusion of the construction project: CHESS-U.

Fourteen months ago, Lt. Gov. Kathy Hochul came to the Cornell High Energy Synchrotron Source (CHESS) to announce a $15 million grant from the New York State Upstate Revitalization Initiative.

The URI funding was for an upgrade project – dubbed “CHESS-U” – which would arm CHESS with enhanced X-ray capabilities, keeping it a leading synchrotron source in the U.S. The project was also expected to create dozens of jobs, both at Cornell and across the region.
On Jan. 17, Hochul returned to Wilson Laboratory, the home of CHESS, to proclaim the project complete in an event that drew local lawmakers, stakeholders from Cornell, and representatives from several local and regional manufacturers whose contributions were on display during a short tour of the new experiment hutches and other equipment.
There is still some work to be done related to the project, and the linear accelerator and synchrotron beams – which were turned off for CHESS-U on June 4, 2018 – aren’t scheduled to be turned back on until Jan. 23. The event marked the official end of the construction project, for which crews worked double shifts over the final six months of 2018 in order to minimize downtime. In addition, wall and ceiling segments for most of the new experiment hutches were built off-sight at Advanced Design Consulting of Lansing and shipped to CHESS for installation. Beamlines will gradually be recommissioned in the coming months.

Tomography beamline at SESAME is officially launched

On 1st January 2019, the European Horizon 2020 project BEAmline for Tomography at SESAME (BEATS) was launched with the objective to design, procure, construct and commission a beamline for hard X-ray full-field tomography at the SESAME synchrotron in Jordan.

The European grant is worth 6 million euros and will span a four-year period from beginning 2019 to end 2022.
Led by the ESRF, the European synchrotron (France), BEATS involves leading research facilities in the Middle East (SESAME and the Cyprus Institute), and European synchrotron radiation facilities ALBA-CELLS (Spain), DESY (Germany), the ESRF (France), Elettra (Italy), INFN (Italy), PSI (Switzerland), SESAME (Jordan) and SOLARIS (Poland). The initiative is funded by the European Union’s Horizon 2020 research and innovation programme.

Nine partner institutes will join forces to lay the groundwork for the efficient and sustainable operation of the SESAME research infrastructure. Through the development and consolidation of the scientific case for a beamline for tomography, and actions to fortify the scientific community, the partners will pay particular attention to the R&D and technology needs of the SESAME Members. Built upon the OPEN SESAME project, BEATS will address the issue of sustainability of operation by preparing medium- to long-term funding scenarios for the tomography beamline and the facility.

Beam us up

The upgrade of the U.S. Department of Energy’s Advanced Photon Source at Argonne National Laboratory will make it between 100 and 1,000 times brighter than it is today.

That factor is such a big change, it’s going to revolutionize the types of science that we can do,” said Stephen Streiffer, Argonne Associate Laboratory Director for Photon Sciences and Director of the APS. We’ll be able to look at the structure of materials and chemical systems in the interior of things — inside a turbine blade or a catalytic reactor — almost down to the atomic scale. We haven’t been able to do that before. Given that vast change, we can only dream about the science we’re going to do.”
In December, DOE approved the technical scope, cost estimate and plan of work for an upgrade of APS.
The APS upgrade has been in the works since 2010. The upgrade will reveal a new machine that will allow its 5,500 annual users from university, industrial, and government laboratories to work at a higher spatial resolution, or to work faster with a brighter beam (a beam with more X-rays focused on a smaller spot) than they can now.

Two more experiment stations start user operation

Facility double experiment capacity.

Two additional experiment stations—or instruments—have now started operation at European XFEL. The instruments for Small Quantum Systems (SQS) and Spectroscopy and Coherent Scattering (SCS) welcomed their first user groups for experiments last week and this week respectively. With the successful start of operation of the new instruments, European XFEL has now doubled its capacity to conduct research. With the first three groups coming to the new instruments in 2018, the total number of users who will have visited the facility in 2018 will reach over 500.
The two already operational instruments, SPB/SFX and FXE, have been used to examine biomolecules or biological processes and ultrafast reactions respectively since September 2017. In the future, two of the four now operational instruments will be run in parallel in twelve hour shifts. Two more instruments are scheduled to start user operation in the first half of 2019.
