New Director for massive upgrade into Diamond-II

To cement its position as a world-leading research facility, Diamond Light Source recently revealed plans for a large upgrade called Diamond-II and that is set to strengthen the UK’s global scientific leadership. This will be a transformational upgrade that will enable a huge expansion of UK science capabilities as it involves a coordinated programme of development combining state-of-the-art technology in a new machine, five new flagship beamlines and a comprehensive series of upgrades to its Instruments.

To lead this programme, Diamond has appointed Rob Walden, a Chartered Engineer with over 20 years’ experience in delivering business and process improvement programmes in the aerospace manufacturing engineering industry. This was followed by several years as a senior projects advisor in central government where he was involved in, and delivered, nationwide policy projects as well as helping to develop the programme delivery framework for government. Rob was also part of the Cabinet Office’s Gateway Assurance review team and conducted a number of forensic assurance delivery reviews for programmes of national interest. Additionally, he helped to set up the national programme office structure for Highways England and ran two busy Project Management Offices.

Rob joined Diamond Light Source from Sellafield Ltd where he focused on raising the standards of the programme delivery framework, which included the appointment and development of the SRO (Senior Responsible Officer) function for major projects of national interest. Rob comments:

For over 15 years Diamond has been a leading centre for synchrotron science on the world stage, supporting UK business and academia to undertake cutting-edge research in a diverse set of areas and sectors. I am delighted to join a team of such esteemed colleagues as we move into the next chapter in Diamond’s life, the detailed planning of the delivery of Diamond-II to secure long-term funding, pushing the boundaries of scientific research even further and keeping the UK at the forefront of scientific research.

#SynchroLightAt75 – The first multi-bend achromat synchrotron light source

At the end of the 1990’s, the MAX-lab management realized that it was necessary to start planning for a possible next step in the development of the laboratory. Although MAX II, one of the first 3rd generation light sources in the world and the flagship of the laboratory, had just recently come into operation, the long lead times made it necessary to start exploring possible further developments already at that stage. This is the saga of MAX IV Laboratory, the world’s first Multi-Bend Achromat (MBA) Synchrotron Radiation Light Source. MBAs strongly focus and guide electrons around the storage ring, creating an ultra-low emittance beam and therefore ultra-bright X-ray radiation.

Someday you will get to play with those electrons!

Razib Obaid is a project scientist at the Linac Coherent Light Source (LCLS) at SLAC in California. LCLS is one of 7 free electron lasers in the collaboration. The facility takes X-ray snapshots of atoms and molecules at work, providing atomic resolution detail on ultrafast timescales to reveal fundamental processes in materials, technology and living things. Its snapshots can be strung together into “molecular movies” that show chemical reactions as they happen.

In Razib’s #LightSourceSelfie, he takes you into the Near Experimental Hall and describes the stunning equipment that is used to undertake the experiments, the science it enables and the possibilities for new science with the upgrade to LCLSII. Razib says, “The best thing about working at a light source is the ability as a user to tap into the enormous scientific resources and experience that exists among the staff and scientists. Not to mention the state of the art instrumentation that you have access to, to realise your science. To my younger self, I would say, keep studying quantum mechanics, someday you will get to play with those electrons.”

New X-ray laser data system will process a million images a second

When upgrades to the X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory are complete, the powerful new machine will capture up to 1 terabyte of data per second; that’s a data rate equivalent to streaming about one thousand full-length movies in just a single second, and analyzing every frame of each movie as they zoom past in this super-fast-forward mode.

Data experts at the lab are finding ways to handle this massive amount of information as the Linac Coherent Light Source (LCLS) upgrades come on line over the next several years.

LCLS accelerates electrons to nearly the speed of light to generate extremely bright beams of X-rays. Those X-rays probe a sample such as a protein or a quantum material, and a detector captures a series of images that reveal the atomic motion of the sample in real time. By stringing together these images, chemists, biologists, and materials scientists can create molecular movies of events like how plants absorb sunlight, or how our drugs help fight disease.

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.
