COMMISSIONING OF THE 100 MEV PREINJECTOR HELIOS FOR THE SOLEIL SYNCHROTRON

HELIOS is the 100 MeV electron linac pre-injector of SOLEIL the new French SR facility [1]. It has been supplied by THALES, as a turn-key system on the basis of SOLEIL APD design. The linac was commissioned in October 2005. This paper will remind the main features of the linac [2] especially on beam-loading compensation, and will give results obtained during the commissioning tests where a special care has been taken for emittance measurements. Specified and measured beam parameters will be compared to show the performance of the entire system.
