DESCRIPTION:Speakers: Vitaliy Lyamkin (NRC "Kurchatov Institute" - PNPI)\n
 New ultracold neutron source based on superfluid helium is being construct
 ing at the PIK reactor for researches in the field of fundamental interact
 ions physics. The use of superfluid helium will allow achieving an UCN den
 sity in the source chamber of 3400 cm-3\, which is an order of magnitude h
 igher than the current UCN density in sources around the world.\nTo create
  this UCN source some important technologies has been developed and implem
 ented: obtaining and maintaining superfluid helium at low temperatures und
 er conditions of heat influx from the reactor\, manufacturing neutron guid
 es with a high UCN reflection coefficient\, developing heat exchangers for
  ultra-low temperatures and obtaining isotopically pure helium-4. \nThe UC
 N source neutron guide system is designed for four scientific stations. Du
 ring the first stage of the source's operation\, it is planned to install 
 an EDM spectrometer with a measurement sensitivity of 1E-27 e∙cm/year an
 d two experiments to measure the neutron lifetime with an accuracy of 0.1 
 seconds using gravitational and magnetic traps.\n\nhttps://indico.particle
