Abstract
The main objective of the Photo Injector Test facility at DESY in Zeuthen (PITZ) is the production of electron beams with minimum transverse emittance at 1 nC bunch charge. PITZ consists of a photo cathode RF gun, solenoids for compensation of the space charge induced emittance growth and a booster cavity. In order to study the emittance evolution along the beam line three Emittance Measurement SYstems (EMSY’s) were installed downstream of the booster cavity [1]. In a first operation period in October 2006 the emittance was measured for gun gradients of about 40 MV/m. A new gun cavity is presently installed at PITZ and conditioning up to a gradient of 60 MV/m is ongoing. In this work we present recent results from measurements of the normalized projected transverse emittance of the electron beam. The emittance is measured using the so called single slit scan technique. Measurements are presented for different gun and booster gradients, solenoid strengths and initial beam size at the photocathode.
