In this talk I will present several initiatives taken by European synchrotron sources towards a more sustainable operation in line with the recommendations of ESFRI report on energy and supply challenges of research infrastructures.
Examples will cover the optimization and reduction in electric power consumption. I will in particular discuss the use of permanent magnets in storage rings as...
The 14 beamlines for the phase I of High Energy Photon Source(HEPS) will produces more than 300PB/year raw data. Efficiently storing, analyzing, and sharing this huge amount of data presents a significant challenge for HEPS.
HEPS Computing and Communication System(HEPSCC), also called HEPS Computing Center, is an essential work group responsible for the IT R&D and services for the facility,...
My talk will focus on nitride semiconductors used for lighting applications. I will give an overview of our group’s soft X-ray spectroscopy at the endstation for inelastic soft X-ray scattering at the REIXS beamline at CLS. We use X-ray absorption (XAS), X-ray emission (XES), Resonant inelastic X-ray scattering (RIXS) and X-ray excited optical luminescence (XEOL) to probe the electronic...
Major synchrotron radiation facilities typically operate under classical access models (CAMs), which are reliable but lack agility and responsiveness for urgent, collaborative, and long-term projects. In response to user concerns, adaptations such as rapid access proposals, block allocation group proposals (BAG), and long-term proposals (LTP) have been implemented alongside the CAMs. However,...
The MID instrument at the European XFEL uses hard X-ray FEL beam to study material dynamics on solid-state systems [1]. We introduce a miniature pulsed magnetic field setup and a sample cryostat that can be installed at the MID interaction chamber to allow an applied magnetic field up to 15 T and sample temperature control from 10 K to 300 K on fixed solid targets. The split-pair coils of the...
XRnanotech, born from the collaborative spirit of the Paul Scherrer Institut, is a vanguard in the evolution of X-ray optics. Our foundation in advanced nanolithography techniques has enabled us to craft optical elements with an unparalleled level of precision, reaching into the single-digit nanometer territory. We harness a diverse array of sophisticated methodologies, including electron-beam...
Many optics at synchrotron and free electron laser facilities need to be cooled to dissipate the heat imparted by the intense photon beams. For indirectly-cooled optics, distortion of the surface caused by excessive clamping forces during assembly, typically utilising Belleville washers with an inaccuracy of approximately 20%, can lead to significant distortion and defocussing of the X-ray...
