TUPD29 | First Measurements of the Longitudinal Phase Space Distribution using the New High Energy Dispersive Section at PITZ | 360 |
|
||
The Photo Injector Test facility at DESY, Zeuthen site, (PITZ) develops and optimizes high brightness electron sources for Free Electron Lasers (FELs) like FLASH and the European XFEL. A new multi-purpose dispersive section was designed* and installed to characterize the momentum distribution, the longitudinal phase space distribution and the transverse slice emittance of the electron bunch for an electron energy up to 40 MeV. The spectrometer consists of a 180 degree dipole magnet followed by a slit, a quadrupole magnet and two screen stations. One of the screen stations is equipped with an optical read-out for a streak camera to measure the longitudinal phase space distribution. The first measurement results and corresponding beam dynamics simulations of the longitudinal phase space and the momentum distributions will be reported in this contribution. The resolution of the system will be analysed and compared to the design expectations. *Sergiy Khodyachykh et al. |
