PROFILE MONITORS FOR THE SwissFEL INJECTOR TEST FACILITY

The SwissFEL Injector Test Facility consists of an RF gun, an accelerating section for a final energy of 250 MeV, and two diagnostics sections. Transverse profiles of the electron beam can be recorded at 27 locations by imaging fluorescent crystals that can be inserted into the beam. At 21 of these, the fluorescent screens are complemented by optical transition radiation monitors and wire scanners. Here, we will evaluate the performance of transverse profile monitors. Profile monitors are used in conjunction with a slit and a pepper pot to determine the transverse phase space distribution of the bunches at low energy. Experimental results from the SwissFEL Injector Test Facility are presented.
