Status of the ALICE Fast Interaction Trigger in RUN 3
The Fast Interaction Trigger (FIT)—a hybrid system of three ALICE forward detectors—has participated in each data-taking session since the beginning of LHC Run 3 in July 2022. FIT is essential for ALICE operation and provides the fastest online trigger, measures precision collision time, charged-particle multiplicity and centrality, and determines the online vertex position. It also serves as the primary online luminometer used by the LHC for beam levelling at ALICE.
