TI - Beam-Based Calibration and Performance Optimization of Cavity BPMs for SwissFEL, E-XFEL and FLASH2
J2 - Proc. of IBIC2014
AB - SwissFEL, the European XFEL (E-XFEL) and FLASH2 all use dual-resonator cavity beam position monitors (CBPMs). The CBPM electronics that is built by PSI has a larger number of calibration parameters that need to be determined in order to maximize the CBPM system performance. Beam measurements with the BPM electronics have been made in BPM test areas at the SwissFEL test injector and FLASH, as well as at FLASH2 where 17 E-XFEL type CBPMs have recently been installed in the undulator intersections [*,**]. The CBPMs are pre-calibrated in the lab using an automated test and calibration system [**], and then the final calibration is done with beam. This report discusses beam-based methods to optimize the system performance by improving the pre-beam system calibration as well as the mechanical alignment of the pickup position and angle.
