Abstract

The SPARC Project has started commissioning its photo-injector. RF gun, RF sources, RF network and control, power supplies, emittance meter, beam diagnostics and control to measure the RF gun beam are installed and working inside the SPARC bunker. The photocathode drive laser has been characterized in terms of pulse shape and quality. We conducted initial beam measurements at RF gun exit using the emittance meter and a spectrometer. Preliminary indications of emittance oscillations driven by space charge in the drift downstream ther RF gun are observed, in agreement to what expected from our theoretical model and numerical simulations. The design of the 12 m undulator for the FEL experiment has been completed and the first undulator section out of 6 is under test: we expect to fully characterize it at Frascati ENEA laboratory within the next months. Recent results of R&D activities on new photocathode materials are also reported.
