During a state visit to Jordan today, His Excellency Frank-Walter Steinmeier, President of the Federal Republic of Germany, took time out to visit the SESAME laboratory north-west of the capital Amman. In November last year, Germany announced its intention to become an Associate Member of SESAME, cementing the country’s already long-standing support for the Laboratory. At the end of his visit, the President signed the Laboratory’s guest book, in the company of SESAME Director Dr Khaled Toukan and young researchers from across the region: “I am fascinated by the succeeding cooperation of so many countries in the Middle East and worldwide. This important work of researchers shows what a treasure international cooperation to the benefit of all of us is. Germany continues to support this place of science in the years to come.”
Germany’s relationship with SESAME goes back to the origins of the laboratory. It was the donation of the BESSY I synchrotron that allowed the fledgling SESAME to establish itself as an intergovernmental organisation in 2004. BESSY I components today form the injector for the SESAME main ring accelerator. Germany has been an Observer to the SESAME Council since its establishment in 2004.
Diamond Light Source hosted a delegation from SESAME in Jordan, marking a renewed commitment to the existing scientific collaboration between the two facilities.
Also in attendance was Professor Dame Angela McLean, the UK government’s chief scientific adviser, a representative of His Excellency Manar M Dabbas, Jordan’s ambassador the UK and Professor Samar Hasnain, the UK’s representative on the SESAME Council since 2004.
The visit marked a new phase in the long-standing relationship between the two synchrotron facilities, which share a mission of advancing scientific excellence and fostering cross-border collaboration.
SESAME, located in Allan, Jordan, is an intergovernmental research centre established under UNESCO and inspired by the cooperative model of CERN. It brings together scientists from across the Middle East and neighbouring regions, serving as a scientific hub of shared research.
The UK has been involved with SESAME since its inception, serving as a founding observer nation and offering guidance and expertise throughout the facility’s development over the past two decades.

Employees of the technology transfer centre ANAXAM and researchers from the Paul Scherrer Institute PSI used the unique analytical methods available at PSI to look inside pre-filled syringes. They found that, in rare cases, zinc from the needle shield can leach into the drug solution to be injected and possibly contribute to syringe clogging.
The task which the employees of the technology transfer centre ANAXAM set themselves, together with colleagues at the Paul Scherrer Institute PSI, can be likened to looking for a needle in a haystack. They were asked by the pharmaceutical company MSD (a trade name of Merck & Co., Inc., Rahway, N.J., USA) to find out whether tiny amounts of the element zinc can get inside the needles of pre-filled syringes and, if so, where it lodges in the needles.
The background is the observation that, in rare cases, the needles of pre-filled syringes (PFS) can become blocked, for example if the syringes are not stored in a cool enough environment. This phenomenon has been known for some time and has already been studied by ANAXAM. However, what has remained unclear is exactly what triggers the blockage. One suggestion was that zinc from the needle shield – the rubber cap into which the needle is inserted when the syringe is manufactured – could leach into the drug solution to be injected, making it more viscous, which would ultimately lead to blockages.
To investigate this theory, the team led by ANAXAM has now resorted to sophisticated methods of detection. These allowed them to look inside the blocked hypodermic needles and check whether and where zinc was present. The results have now been published in the journal Pharmaceutical Research.
Convenient pre-filled syringes
Pre-filled syringes are widely available, practical and easy to use, both for healthcare professionals and for patients. The amount of solution to be injected is precisely measured, which virtually rules out dosing errors, for example. The fact that their needles can become clogged, especially when the solution to be injected is highly concentrated, is a well-known issue in the pharmaceutical industry and has also been raised during licensing applications. There have also been cases of clogged needles which have led to products being recalled. “So Merck was very interested in knowing whether zinc could in fact find its way into the needles and cause the blockage,” says Vlad Novak, project manager at ANAXAM.
This meant that several questions had to be answered. Is there zinc inside the needle? And if so, where do they come from? What does the inside of a clogged needle look like? And is the zinc also present in the solution being injected, which could ultimately lead to the blockage?

Last week, Lightsources.org travelled to Hamburg to be part of one of the community’s most popular events, the Synchrotron Radiation Instrumentation (SRI) conference. The SRI conference is regarded as the world’s most important exchange forum for experimenters, developers and operators of large X-ray radiation sources.
SRI2024 was organised by DESY and the European XFEL and attracted over 1000 experts from all over the world. The conference gave Lightsources.org the perfect opportunity to celebrate its 20th Anniversary with scientists and technical experts from facilities, academic institutes and companies within the international light source community.
As a collaboration of science communicators, Lightsources.org organised a series of events and activities aimed at raising the profile of its members, which include 24 synchrotrons and 8 Free Electron Lasers. An additional focus involved recognising the science and science communication talents of conference attendees through two poster prize competitions.
Isabelle Boscaro-Clarke, Head of Communications, Engagement and Impact at Diamond and Vice-Chair of Lightsources.org, comments, “It was a real honour for Lightsources.org to be part of this wonderful conference. Our collaboration of science communicators exists to provide one voice for the light source community. It was inspiring to meet so many delegates and exhibitors who share our passion for these amazing facilities and the incredible science they deliver.”
Lightsources.org is particularly keen to support early career professionals and, to support this goal, two lunchtime sessions were offered during the conference. The session on Wednesday, which was chaired by Isabelle Boscaro-Clarke, focused on career insights and development with a panel of senior leaders including Gianluigi Botton, Diamond Light Source, Sakura Pascarelli, the European XFEL, Britta Redlich, HFML – FELIX and LEAPS, Laurent Chapon, Argonne (APS) and Gerd Materlik, UCL.
The second session on Thursday put the spotlight on science communication and gave participants the opportunity to practice and develop their communication skills.

This is a story of miles and nanometers. Celline Awino Omondi and Miller Shatsala traveled from Kakamega, Kenya, to Berkeley, USA, through a grant from Lightsources for Africa, the Americas, Asia, Middle East, and Pacific (LAAAMP), a journey of over 9,400 miles. Their research interests, however, are best described with nanometers—very thin perovskite films to be used for solar energy.
At their home institution, Masinde Muliro University of Science and Technology, Omondi is a faculty member and Shatsala is a PhD student in the department of physics. Omondi’s interest in new materials began in graduate school. “I did a master’s in materials nanotechnology, and it was so interesting, I wanted to continue in materials science,” she said. Though her doctoral studies were in Germany, her research inspiration was closer to home. “In Africa, we have abundant solar radiation. So, we are looking for a way to tap into that solar radiation so that we can use it for our daily life.”
Omondi envisions many applications for photovoltaics. With the new materials under development, solar energy could be used in the future for everything from household electricity to vaccine storage in hospitals and irrigation on farms. New materials to harness solar energy would be life changing. “Most parts of Africa aren’t on the grid, and if they have electricity, it’s very expensive,” Omondi explained.
Similarly, Shatsala’s master’s thesis research focused on silicon solar cells. “Then I discovered that there are new materials coming up in solar energy whose efficiency was almost passing silicon, so that’s why I shifted to perovskites,” he said.
To characterize the perovskites they’re studying, the two researchers came to the Advanced Light Source through a LAAAMP Faculty-Student (FAST) Teams grant. The program provides financial support for PhD students and their faculty advisors from Africa, the Caribbean, Mexico, Central Asia, Southeast Asia, the Middle East, and Pacific to spend two months in residence at a collaborative partner light source. With this training opportunity, scientists like Omondi and Shatsala will be able to take their newfound skills and knowledge back to a region that is still in the planning phases for its own synchrotron facility. One day in the future, the two researchers could be part of operating and using this facility—the African Light Source. “We were privileged to be picked to be among the few people in Africa to come to the ALS,” said Shatsala.
The National Synchrotron Radiation Research Center (NSRRC) commemorated the “30th Anniversary of First Light” on October 23rd. Premier Chien-Jen Chen of the Executive Yuan graced the occasion with his presence and delivered an address. He highlighted NSRRC’s steady and solid progress over the past three decades, from the “Taiwan Light Source (TLS)” to the “Taiwan Photon Source (TPS),” making it Taiwan’s largest R&D platform. Premier Chen envisions NSRRC as a key player in advancing Taiwan’s industry, academia, and research through its unique scientific and technological strengths. He underscored the imperative for NSRRC to sustain its R&D momentum, thus laying a solid foundation for Taiwan’s science and technology sector.
NSRRC hosts over 2,000 researchers annually from 20 countries, totaling 12,000 visits to utilize its exceptional synchrotron radiation capabilities for research purposes. The successful establishment of the TPS experiment facilities boosts utilization. Premier Chen emphasized the vital roles of both TLS and TPS in material development, cancer detection, biomedicine, pharmaceuticals, and achieving net-zero carbon emissions. NSRRC’s diverse contributions solidify its importance in Taiwan’s scientific and technological progress.
In addition to Premier Chen, notable guests included Deputy Minister of the National Science and Technology Council, Minn-Tsong Lin; former President of Academia Sinica, Yuan-Tsehn Lee; and esteemed Academicians Luo-Chuang Lee, Maw-Kuen Wu, Lih-Juann Chen, Chien-Te Chen, and Yu Wang. Also present were the Directors of the Taiwan Space Agency, the National Center for High-Performance Computing, and the Taiwan Instrument Research Center: Jong-Shinn Wu, Chau-Lyan Chang, and Cheng-Tang Pan, respectively. These attendees witnessed the inception, growth, and flourishing of Taiwan’s synchrotron radiation development.

To celebrate International Day of Light 2023, we bring you a #LightSourceSelfies special (see below) from Ludmila Leroy, a postdoc at the Swiss Light Source (SLS), which is located at the Paul Scherrer Institut (PSI) in Villigen, Switzerland. With an energy of 2.4 GeV, the SLS provides photon beams of high brightness for research in materials science, biology and chemistry.
Ludmila, who is from Brazil, is studying the properties of magnetic materials. She highlights the versatility of light sources as hugely advantageous to science and learning from, and about, nature. “We are all driven by curiosity and these versatile facilities gives us the ability to try different approaches and push the boundaries in our experiments.” Looking back on her career to date, Ludmila would advise her younger self “not to be scared to reach out for the world” as there are many light sources facilities around the globe and travelling to different countries is an exciting part of being a scientist.
As with all light sources, the SLS operates around the clock and Ludmila has a new take on making night shifts more bearable. Throughout the #LightSourceSelfie campaign, most participants have mentioned coffee, chocolate or candy when talking about night shift survival strategies. For Ludmila, night shifts are more bearable when she eats healthily and makes sure that she keeps hydrated.
And when she is not at a light source….Ludmila is in charge of the Music Club at PSI, which brings together a mixture of PhD students, postdocs, technicians and staff scientists. The PSIchedelics is just one of the society’s musical entertainment offerings. Ludmila plays the bass and sings in this band and her #LightSourceSelfie ends with a fantastic clip of them in action.

From magnets to power supplies, NSLS-II experts support accelerator upgrades across the Nation.
Each year, thousands of people travel far and wide to see architectural marvels such as the towering steps of the Kukulcán temple in in Chichen Itza or the intricate facade of the Cologne Cathedral in Germany. Like these marvels of history and culture, thousands of researchers travel to the U.S. Department of Energy’s (DOE’s) five light source facilities each year. They don’t come for the views, though, they come to push the boundaries of science—in fields ranging from batteries to pharmaceuticals—by using the ultrabright synchrotron light, mostly x-rays, from these facilities to conduct experiments.
This light doesn’t just appear out of nowhere. It needs to be generated by large, complex particle accelerators. And, to keep the x-rays as bright as possible, scientists and engineers are working constantly to advance them. This story highlights ongoing collaborative projects of the Accelerator Division at the National Synchrotron Light Source II (NSLS-II), located at DOE’s Brookhaven Lab.
According to historical sources, it took the Germans over 600 years to build the original Cologne Cathedral, while archeologists speculate that the Temple of Kukulcán took at least 200 years to build in two phases. Thousands of people worked on these monuments during these extremely long construction periods. This is a feat they share with modern particle accelerator projects. While the initial construction of NSLS-II took only a decade, it still involved an international effort of hundreds of people from many disciplines and professions.
From the civil engineering challenges of the building design to the construction of the hundreds of magnets inside the accelerator, it truly takes more than a village to build a particle accelerator for a synchrotron light source. Similarly, many modern accelerator projects span multiple institutions and countries to leverage the expertise in the field.

An international team of scientists have unveiled details of the history of the asteroid Ryugu, a truly ancient object in the Solar system, after the Hayabusa2 mission brought samples from this asteroid back to Earth. The ESRF was one of the institutes involved in sample characterization, on ID15A. The results are published in Science.
The asteroid Ryugu, located at 200 million kilometres from the Earth, is one of the most primitive objects of the solar system. The Japanese spacecraft Hayabusa2 explored it from 2018 until it came back to Earth two years later with minuscule multiple samples from the asteroid.
Two years later, and thanks to the international collaboration of institutes led by the Japan Aerospace Exploration Agency (JAXA), the first results on the analysis of the samples shed light on the history of Ryugu, from its formation to its collisional destruction.
Researchers used cosmochemical and physical methods at universities and institutes, including the ESRF and four other synchrotron radiation facilities in Japan, United States, and Europe.
The results combined with computer simulation have allowed scientists to picture the origins of Ryugu: the Ryugu parent body accumulated about 2 million years after the formation of the solar system, and then heated up to about 50°C over the next 3 million years, resulting in chemical reactions between water and rock. The size of the impactor that destroyed the Ryugu parent body, which is about 100 km in diameter, is at most 10 km in diameter, and that the present-day Ryugu is composed of material from a region far from the impact point.
What the data explain
In particular, the seventeen Ryugu samples analysed contain particles (such as Ca- and Al-rich inclusions) that were formed in high-temperature environments (>1000°C). These high-temperature particles are thought to have formed near the Sun and then migrated to the outer solar system, where Ryugu was formed. This indicates that large-scale mixing of materials occurred between the inner and outer solar system at the time of its birth.
Based on the detection of the magnetic field left in the Ryugu samples, it is highly likely that the original asteroid from which the current Ryugu descended (Ryugu’s parent body) was born in the darkness of nebular gas, far from the Sun, where sunlight cannot reach.
The scientists also discovered liquid water trapped in a crystal in a sample. This water was carbonated water containing salts and organic matter, which was once present in the Ryugu parent body. Crystals shaped as coral reefs grew from the liquid water that existed inside Ryugu’s parent body. Rocks that were deeper underground contained more water than those in the surface.
