First experience with tomographic reconstruction in PITZ — •Galina Asova, Mikhail Krasilnikov, and Frank Stephan — Platanenalle 6, 15738 Zeuthen

The Photo-Injector Test Facility at DESY, Zeuthen site (PITZ), is dedicated to development and test of high brightness electron sources for linac-based FELs. The PITZ beamline is equipped with three dedicated stations for transverse emittance measurements and in the current shutdown period a section for transverse phase-space tomography diagnostics is being installed. The reconstruction algorithms for analysing the data obtained with the tomography setup are currently pre-evaluated with multiple projections of quadrupole scan data taken at PITZ.

This work will present first experience with tomographic reconstruction from quadrupole scan data. Measurements of the transverse phase space of electron beams produced with gaussian and flat-top temporal laser pulses are presented and superimposed to simulated data. The results are also compared to those obtained with single slit technique.
