35. MICE DAQ Terminology • Isis Cycle: • The injection and acceleration cycle of ISIS. It is 20 ms long (50 Hz). • Machine Start (MS): • This is the pulse used for the ISIS synchronization • Spill Gate: • Time window during which the MICE Target is crossing the ISIS beam. Driven by the cycle of the MICE target. • Burst: • The ~100 ns time window during which muons are in the MICE detectors. Is the time it takes for a proton bunch in ISIS to cross through the MICE target. • DAQ-Trigger: • Signal triggering the readout of the FE-electronics modules of the MICE detectors. One DAQ-Trigger = one DAQ-Event • Particle-Trigger: • Signal generated when the desired Trigger Condition is met. • Distributed to the sub-detectors Front End Electronics and initiates the digitization of the data.
