NEUTRON DETECTOR Russian patent published in 2012 - IPC G01T3/00 

FIELD: physics.

SUBSTANCE: neutron detector has a source of charged particles arising under the action of neutron radiation and an elastic member, wherein the source of charged particles is made from stable, non-radioactive material. A charged particle absorber is placed opposite the source of charged particles. At least one optical fibre with a reflecting end face is placed in the housing of the sensor. An optical mirror is mounted on the elastic member.

EFFECT: avoiding fissile material, eliminating restrictions on measured flux and fluence, high noise-immunity, high reliability of measurements and the neutron detector, enabling measurement of the time dependency of flux in case of pulsed neutron sources, providing the required triggering threshold by optical means when starting up the detecting equipment, enabling multiple use and easy technical implementation.
