Model based algorithm to specify the alignment of the bERLinPro photoinjector components — •Jens Völker and Bettina Kuske — Helmholtz Zentrum Berlin, Berlin, Deutschland

The photoinjector module for bERLinPro will be assembled in the beginning of 2020 and will be installed in the bERLinPro injector beamline afterwards. Due to tight installation shedule, it is not possible to operate the assembled module prior to installation. Thus, module components like the SRF gun cavity, SC Solenoid or photocathode, can only be pre-adjusted in the warm state. However, they can be remotely adjusted in the module during operation. Therefore, a method is needed to quantify the alignment and other parameters of module components based on electron beam measurements with the aid of only limited diagnostic tools. With scans of known module parameters and the measurement of the changing beam response, this method should quickly clarify the alignment status and helps to adjust important components. In this talk, we will present the algorithm and simulation results.
