SIRIUS is a Brazilian fourth-generation synchrotron light source, having its first stored beam in December 2019. Currently, the facility runs in top-up mode with 100 mA while accelerators get constant upgrades and improvements to reach project specifications. There are 10 beamlines already in operation with regular users call, and new ones are under installation/ commissioning/ development for...
MAX IV is a synchrotron radiation facility based on a 3 GeV linear accelerator, which powers a soft and hard x-ray storage ring, as well as a short pulse facility. For these three subsystems, a rigorous downtime record is kept, classified according to a comprehensive list of root causes. Recently, the storage rings at MAX IV have had an increase in downtime events without a clear root cause....
Synchrotron SOLEIL is the French 3rd generation synchrotron light source. It has been in operation since 2007, providing photon beams to 29 beamlines with a maximum intensity of 500 mA, 5000 hours per year.
In the second half of 2023, the SOLEIL cryogenic operations team experienced a very stressful operation situation with the helium refrigeration plant of the storage ring (SR)...
Run 23 for the Relativistic Heavy Ion Collider saw the return of two collision points for the first time since 2016 using Au-Au collisions for the commissioning of the new sPHENIX detector and a physics run for the STAR collaboration. The run was cut short by 6 weeks when a warm-to-cold power connection failed for the main ring power supplies. An exhaustive investigation showed several...
