The impact of linear space charge on the tomographic reconstruction at PITZ — •Georgios Kourkafas1, Mikhail Krasilnikov1, Dmitriy Malyutin1, Barbara Marchetti1, Frank Stephan1, and Galina Asova2 — 1DESY, 15738 Zeuthen, Germany — 2INRNE-BAS, 1784 Sofia, Bulgaria
The Photo Injector Test facility at DESY, Zeuthen site (PITZ) focuses on testing, characterizing and optimizing high brightness electron sources for free electron lasers. Among various diagnostic tools installed at PITZ, the tomography module is used to reconstruct the transverse phase space distribution of the electron beam by capturing its projections while rotating in the phase space. This diagnostic technique can resolve the two transverse planes simultaneously with an improved resolution for pulses of low charge or in the future even for individual bunches within a bunch train.
The low emittance, high charge density and moderate energy of the electron beam at PITZ contribute to significant space-charge forces. The conducted study aims to investigate how the phase space rotations and thus the reconstruction result are affected when considering the linear space-charge effect along the tomography lattice. The beam dynamics simulations were done using the V-Code tool.
