One of the primary tasks of the Photo Injector Test Facility at DESY in Zeuthen (PITZ) is to characterize and optimize L-band photo-electron sources for use at FLASH and European XFEL. AT PITZ, the transverse phase space of 17-20 MeV electron beams are measured using a single slit scan and scintillator screen method. With the trend in photoinjectors towards lower current and emittance,...
A method to measure relative changes of the bunch length based on the spectrum of the induced voltage on a BPM button has been developed at ALBA. The bunch length has been calibrated using a Streak Camera for different filling patterns and beam currents. The idea is to have an alternative, redundant and readily available measurements of the bunch length during machine operation, avoiding the...
