The CALIFA trigger system — Leyla Atar1, Tobias Jenegger2, Roman Gernhäuser2, •Philipp Klenze2,3, and Lukas Ponnath2 for the R3B collaboration — 1Technische Universität Darmstadt — 2Technische Universität München — 3Gesellschaft für Schwerionenforschung, Darmstadt
With the recent completion of the forward region of the R3B calorimeter, CALIFA now features 1504 channels. While previously each channel of CALIFA was operated in free-running mode, recent beamtimes have shown that this puts a huge load on the downstream processing facilities especially in experiments using high rate uranium beams.
Due to the slow signals of the calorimeter CsI(Tl) crystals special procedures have been established not to compromise efficiency. Using the White Rabbit Time Stamps (WRTS) differences of various detector systems, it is easy to verify that this is actually the case.
Additionally, we will discuss the ability of CALIFA to provide a high level trigger based on proton multiplicities or position to ancilliary detectors with limited readout capability in R3B.
