Progress on the PITZ TDS

A transverse deflecting system (TDS) is under commis-sioning at the Photo Injector Test Facility at DESY, Zeuthensite (PITZ). The structure was designed and manufacturedby the Institute for Nuclear Research (INR RAS, Moscow,Russia) as prototype for the TDS in the injector part of theEuropean XFEL. Last year the deflection voltage was lim-ited for safety reasons, but after thorough investigations ofthe waveguide system we are now able to operate the cav-ity close to design specifications. The PITZ TDS streaksthe electron beam vertically, allowing measurements of thelongitudinal bunch profile, and, in combination with a sub-sequent horizontal bending magnet, also of the longitudinalphase space and slice energy spread. Furthermore, severalquadrupole magnets and screen stations can be employedfor horizontal slice emittance measurements using the TDS.This paper describes the progress in commissioning of thehardware, measurement techniques and simulations, andoutlines the prospects of reliable slice emittance measure-ments at 20 MeV/c, where space charge forces complicatethe determination of transfer matrices
