Project summary

Development of the project of a pulsed source of slow neutrons (cold, thermal, resonant) for researches on fundamental problems of elementary interactions, physics of condensed matter and nuclear physics with an experimental and calculation substantiation of the basic technical offers and decisions.

In a basis modernization of existing and working linear proton accelerator of INR RAS (rise of energy up to -700 MeV), constructing storage ring (up to -1014 protons in a cycle), development of subcritical multiplying neutron target by average power -10 MW with liquid gallium cooling.

Expected, parameters of a neutron source will allow to develop new generation of fundamental researches, researches for solid state physics, structures of nuclei and mechanism of nuclear reactions at experiments sensitivity, inaccessible by other ways.

As one of the basic fundamental experiments search of neutron-antineutron occillation in a flux of cold neutrons for check of the great unification theories (GUT) is supposed.

Pulse density of a flux of thermal neutrons ~ 1017 neutr/cm2sec.

Average density of a flux of thermal neutrons ~ 8*1013 neutr/cm2sec.

Frequency of pulses 25-50 Hz.

Duration of pulses of fast neutrons ~ 1,5 msec, thermal ~ 30 msec.
