DESCRIPTION:Speakers: Georgyi Taer (NRC KI)\nNeutron detection is based on
  the registration of secondary charged particles arising in nuclear reacti
 ons with the detector material. The efficiency is determined by the reacti
 on probability and the linear dimensions/material of the detector. \nFor t
 ime-of-flight measurements\, fast scintillators or gas detectors are usual
 ly used. A promising improvement is to replace part of the passive layers 
 with active layers made of bismuth orthogermanate (Bi₄Ge₃O₁₂\, BGO
 ). BGO is characterized by high density ($\\rho$ ≈ 7.13 g/cm³)\, low ra
 diation length (~1.13 cm)\, radiation resistance\, absence of afterglow\, 
 and a light yield of ~7000 photons/MeV. The absence of cleavage planes all
 ows the crystals to be shaped into any form. Due to its higher density com
 pared to NaI(Tl) and CsI(Tl) and other popular scintillators\, BGO provide
 s higher efficiency in detecting photons and neutrons for the same volume.
  However\, the high density causes partial self-absorption of photons\, re
 ducing the signal amplitude\, which is compensated for by modern electroni
 cs with a high signal-to-noise ratio. \nA significant drawback of heavy sc
 intillators is the long rise time of the signal (>100 ns)\, which makes th
 eir use for the time-of-flight method difficult. Nevertheless\, the requir
 ements for the neutron detector being developed include the possibility of
  using the time-of-flight (TOF) method. \nThis paper demonstrates the fund
 amental possibility of using BGO for the TOF method.\n\nhttps://indico.par
