DESCRIPTION:Speakers: Alla Maevskaya  (INR RAS)\nDuring the upcoming Run 3
  and Run 4 at the LHC the upgraded ALICE (A Large Ion Collider Experiment)
  will operate at a significantly increased luminosity and bunch crossing a
 nd will collect two orders of magnitude more events than in Run 1 and Run 
 2. A part of the ALICE upgrade is the new Fast Interaction Trigger (FIT) [
 1]. This thoroughly redesigned detector combines\, in one system\, the fun
 ctionality of four forward detectors used by the ALICE experiment during t
 he LHC Run 2: T0\, V0\, FMD and AD. As part of the online functionality\, 
 FIT will monitor luminosity and background\, provide real-time feedback to
  the LHC\, and generate minimum bias\, vertex and centrality triggers. Dur
 ing the offline analysis FIT data will be used to extract the precise coll
 ision time needed for time-of-flight particle identification. During the h
 eavy-ion collisions\, FIT will also determine multiplicity\, centrality an
 d event plane. FIT electronics is designed to function both in the continu
 ous and the triggered readout mode.\n\nIn this presentation I will describ
 e the FIT simulation software and raw data processing. The focus will be o
 n the detector performance\, especially\, triggers efficiencies\, collisio
 n time and centrality resolution.\n\n \n\nReferences\n\n[1] W. H. Trzaska.
