New trigger concepts for future measurements at the M2 beam line at CERN — •Benjamin Moritz Veit — CERN and Institut für Kernphysik der Johannes Gutenberg-Universität, Mainz, Deutschland
Currently proposals are being prepared for future measurements with muon and hadron beams at the M2 beam line of the CERN SPS. It is mandatory for these experiments to have a new digital trigger system, which can handle the high rates at the M2 beam line and is flexible in design to adapt for the different planed physics programs. One of the planed experiments is the measurement of the proton radius by elastic muon proton scattering. For this measurement the trigger system has to be sensitive to very small scattering angles for low Q2 events resulting in very high rates. The new trigger system has to be integrated in the main DAQ and is based on an continuous readout of fast detectors like hodoscopes and scintillating fibre stations. The handling of the triggerless data stream is done by a network of FPGAs performing the multi level trigger decision.
This talk will summarize the plans and the current status of the development of such a trigger-system.
