FIRST TESTS OF THE TOP-UP GATING AT SYNCHROTRON SOLEIL

Since 2006, Synchrotron SOLEIL is producing photons. The beamlines became operational for the users in 2008. Until 2012, thanks to the excellent performances of the injection system of the storage ring, the perturbation on the position of the stored beam during Top-up injection was small enough to be accepted by the users. For some specific experiments requesting higher beam stability, few beamlines expressed their wish to be able to freeze the data acquisition during the injection. To fulfill this need, the diagnostics group of Synchrotron SOLEIL designed the “TimEX3” board which was integrated into the timing system in order to allow 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.
