  The goal of the Photoinjector Test Facility at DESY in Zeuthen (PITZ) is to test and optimise electron guns for FELs like FLASH at DESY in Hamburg. In 2005 the setup was extended by a booster cavity. In order to measure longitudinal and transverse beam properties in the range between 5 to 40 MeV/c, a viewport after the booster cavity was developed. It contains several radiators. One of them is Silica aerogel used as Cherenkov radiator for the measurement of the longitudinal electron distribution with a streak camera. Design considerations are presented and maybe first measurement results are available. The longitudinal distributions after the booster for different beam parameters are compared to the distributions before the booster.
