DESCRIPTION:Speakers: Oleg Markin (ITEP\, MEPhI)\nIn the COMET experiment 
 searching for the muon-electron conversion not conserving leptonic numbers
 \, a scintillator-strip-based veto system will be used to prohibit the COM
 ET detector from fake signals initiated by cosmic muons. In order to verif
 y the efficiency of the system\, we have built its computer model and carr
 ied out various simulations. To tune the model\, experimentally measured d
 ata are utilized. The simulations give the inefficiency of the cosmic-muon
  registration being below 0.0001\, which meets requirements  of the experi
 ment. In addition\, simulations of neutrons traversing a shield beneath th
 e cosmic-veto system have been carried out using the Geant4 toolkit. A Gea
 nt4 application has been written with an appropriate detector design and  
 possible spectrum of neutron's energy. Design of the shield is optimized t
 o ensure the time loss concerned  with fake veto signals caused by the neu
 trons from muon captures in target is tolerable. Materials of shield's lay
 ers are chosen\, and optimum thicknesses of the layers are computed.\n\nht
