DESCRIPTION:Speakers: Tatiana Karavicheva (INR\,RAS)\nAs a result of the L
 HC injectors upgrade after the Long Shutdown (2019-2020)\,\nthe expected P
 b-Pb luminosity and collision rate during the so called Runs 3 and 4\nwill
  considerably exceed the design parameters for several of the key ALICE\nd
 etectors systems including the forward trigger detectors. Fast Interaction
  Trigger\n(FIT) will be the primary forward trigger\, luminosity\, and col
 lision time\nmeasurement detector. It will also determine multiplicity\, c
 entrality\, and reaction\nplane of heavy ion collisions. FIT is expected t
 o match and even exceed the\nfunctionality and performance currently secur
 ed by three ALICE sub-detectors: the\ntime zero detector (T0)\, the VZERO 
 system\, and the Forward Multiplicity Detector\n(FMD). FIT will consist of
  two arrays of Cherenkov radiators with MCP-PMT\nsensors and of a single\,
  large-size scintillator ring. Because of the presence of the\nmuon spectr
 ometer\, the placement of the FIT arrays will be asymmetric: ~800 mm\nfrom
  the interaction point (IP) on the absorber side and ~3200 mm from IP on t
 he\nopposite side. The ongoing beam tests and Monte Carlo studies verify t
 he physics\nperformance and refine the geometry of the FIT arrays .The pre
 sentation gives a\nshort description of FIT \, triggers and readout requir
 ement for the ALICE\nUpgrade\, a summary of the performance\, and the outc
 ome of the simulations and\nbeam tests.\n\nhttps://indico.particle.mephi.r
