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.
期刊介绍:
Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
