Recent Developments at PITZ / Krasilnikov, Mikhail ; Abrahamyan, Karen ; Ackermann, Wolfgang ; Asova, Galina ; Bähr, J W ; Carneiro, Jean-Paul ; Dimitrov, Gancho ; Flöttmann, Klaus ; Gensch, Ulrich ; Grabosch, H J et al.
The ability to produce high brightness electron beams as required for modern Free Electron Lasers (FELs) has been demonstrated during the first stage of the Photo Injector Test Facility at DESY Zeuthen (PITZ1). The electron source optimization at PITZ1 was successfully completed, resulting in the installation of the PITZ rf gun at the VUV-FEL (DESY, Hamburg). [...]

Beam-Based Procedures for RF Guns / Krasilnikov, Mikhail ; Bähr, J W ; Grabosch, H J ; Hartrott, Michael ; Hui Han, Jang ; Miltchev, Velizar ; Oppelt, Anne ; Petrosyan, Bagrat ; Staykov, Lazar ; Stephan, Frank
A wide range of rf photo injector parameters has to be optimized in order to achieve an electron source performance as required for linac based high gain FELs. Some of the machine parameters can not be precisely controlled by direct measurements, whereas the tolerance on them is extremely tight. [...]

Dark Current and Multipacting in the Photocathode RF Guns at PITZ / Hui-Han, Jang ; Bähr, J W ; Flöttmann, Klaus ; Grabosch, H J ; Hartrott, Michael ; Krasilnikov, Mikhail ; Michelato, Paolo ; Miltchev, Velizar ; Monaco, Laura ; Oppelt, Anne et al.
For photocathode rf guns, the amount of dark current depends on the cavity surface and the photocathodes. Smooth conditioning reduces the amount of dark current. [...]

Emission Mechanisms in a Photocathode RF Gun / Hui-Han, Jang ; Bähr, J W ; Flöttmann, Klaus ; Grabosch, H J ; Hartrott, Michael ; Krasilnikov, Mikhail ; Michelato, Paolo ; Miltchev, Velizar ; Monaco, Laura ; Oppelt, Anne et al.
In photocathode rf guns, emission mechanisms at the photocathode play a crucial role in the overall beam dynamics. A low bunch charge as well as a short Gaussian bunch profile allow us to study the beam dynamics depending on emission phase without space charge force. [...]
