DESCRIPTION:Speakers: Alexey Fomin (PNPI NRC KI)\nThe neutron instrument c
 omplex "Neutron Beta Decay" is currently being manufactured to be located 
 on the beam of polarized cold neutrons on the GEK-3 N0 channel. The facili
 ty is designed to measure the electron\, neutrino\, and electron-neutrino 
 asymmetries of neutron beta decay. The experiment is necessary because the
  results of the most recent\, most precise neutron decay experiments\, con
 ducted at an accuracy level of 10$^{−3}$\, cannot be described within th
 e Standard Model. The basis of the facility is a superconducting solenoid\
 , which generates a uniform magnetic field of 0.35 T. Electrons and proton
 s produced during neutron decay move in a magnetic field along magnetic fi
 eld lines. To select a specific electron emission angle\, a magnetic mirro
 r effect is used by creating a region with a stronger magnetic field\, wit
 h an induction of 0.88 T. The decay region is selected by protons\, which 
 are further accelerated by an electric field. This is achieved by using an
  electrostatic system that increases the voltage in the decay region to 30
  kV. Detectors at the input and output of the neutron beam are used to rec
 ord the electrons and protons. The aim of the experiment is to improve the
  accuracy of measuring correlation coefficients by ~3 times. Comprehensive
  simulation of the experiment was carried out.\n\nhttps://indico.particle.
