/ Groß, Matthias (DESY, Zeuthen) ; Boonpornprasert, Prach (DESY, Zeuthen) ; Brinkmann, Reinhard (DESY) ; Chen, Ye (DESY, Zeuthen) ; Engel, Johannes (DESY, Zeuthen) ; Good, James (DESY, Zeuthen) ; Grüner, Florian (CFEL, Hamburg ; Hamburg U.) ; Huck, Holger (DESY, Zeuthen) ; Isaev, Igor (DESY, Zeuthen) ; Krasilnikov, Mikhail (DESY, Zeuthen) et al.
The self-modulation instability is fundamental for the plasma wakefield acceleration experiment of the AWAKE (Advanced Wakefield Experiment) collaboration at CERN where this effect is used to generate proton bunches for the resonant excitation of high acceleration fields. Utilizing the availability of flexible electron beam shaping together with excellent diagnostics including an RF deflector, a supporting experiment was set up at the electron accelerator PITZ (Photo Injector Test facility at DESY, Zeuthen site), given that the underlying physics is the same.

Observation of High Transformer Ratio Plasma Wakefield Acceleration
/ Loisch, Gregor (DESY, Zeuthen) ; Asova, Galina (DESY, Zeuthen ; Sofiya, Inst. Nucl. Res.) ; Boonpornprasert, Prach (DESY, Zeuthen) ; Brinkmann, Reinhard (DESY) ; Chen, Ye (DESY, Zeuthen) ; Engel, Johannes (DESY, Zeuthen) ; Good, James (DESY, Zeuthen) ; Gross, Matthias (DESY, Zeuthen) ; Grüner, Florian (U. Hamburg (main) ; CFEL, Hamburg) ; Huck, Holger (DESY, Zeuthen) et al.
Particle-beam-driven plasma wakefield acceleration (PWFA) enables various novel high-gradient techniques for powering future compact light-source and high-energy physics applications. Here, a driving particle bunch excites a wakefield response in a plasma medium, which may rapidly accelerate a trailing witness beam. [...]

Recent Results and Perspectives of the Low Emittance Photo Injector at PITZ
/ Stephan, Frank ; Bähr, Jürgen ; Gensch, Ulrich ; Grabosch, Hans Jürgen ; HuiHan, Jang ; Krasilnikov, Mikhail ; Lipka, Dirk ; Miltchev, Velizar ; Oppelt, Anne ; Petrosyan, Bagrat et al.
The Photo Injector Test Facility at DESY Zeuthen (PITZ) was built to study the production of minimum transverse emittance electron beams for Free Electron Lasers. In November 2003 the electron beam from the RF gun was fully characterized at PITZ. [...]

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. [...]
