  After six years of operation, equipment located close to some vacuum chambers of the SOLEIL storage ring show unexpected damages due to radiation. It has been pointed out that, inside the so called “quadrupole” vacuum chambers, fluorescence X-rays are emitted by the materials that intercept upstream dipole synchrotron radiation. The energy of the emitted X-ray is too high to be significantly attenuated by the aluminum of which the vacuum chamber is made. Diagnostics and means used to characterize this radiation are presented, and measurements are compared to calculations.

WEPC39 First Tests of the Top-up Gating at Synchrotron SOLEIL 775

  Since 2006, Synchrotron SOLEIL is delivering photons to its beamlines. Until 2012, thanks to the excellent performances of the injection system of the storage ring, the perturbation on the position of the stored beam was small enough to be accepted by the users. For some specific experiments, few beamlines expressed their wish to be able to stop their data acquisition during the injection. To fulfill this need, the diagnostics group of Synchrotron SOLEIL has designed the “TimEX3” board which was integrated into the timing system allowing the gating of the Top-up injection. This design was released as open hardware. Towards this aim, we decided to design it with the open source and free EDA software “KiCad”, and to make it available under the CERN’s Open Hardware Repository.
