Development of a precision timing system for beam background characterization using plastic scintillators — •Florian Eisele1, Fabian Hummer1, and Luca Scomparin2 — 1Institute for Data Processing and Electronics, KIT — 2SLAC National Accelerator Laboratory
Many facilities employ beam loss monitors that report time-averaged loss rates and do not support precise time-of-arrival measurements. We developed an FPGA-based read-out system that, in combination with plastic scintillator detectors, enables beam loss measurements with sub-nanosecond time resolution over multi-second acquisitions. After calibrating the system with cosmic particles, we commissioned this system at the (50 - 500 MeV) booster synchrotron of the Karlsruhe Research Accelerator (KARA). This measurement campaign demonstrated the potential of this new technique. First, we characterized the beam background with nanosecond-level timing precision. Second, we acquired the accelerator clock and injection triggers, in order to correlate the beam background with beam injection, storage and extraction. We prove that the revolution timing structure of the beam current is present in the beam loss. In addition, we showed versatility of the readout system to sample the signals of a stripline sensor at the KARA main ring. In this contibution, we present the FPGA based data acquisition system, first commissioning results and discuss future applications of this technique.
