CHERENKOV'S DETECTOR FOR REGISTRATION OF GAMMA EMISSION IMPULSES OF NANO- AND SUBNANOSECOND DURATION Russian patent published in 2009 - IPC G01T1/22 

FIELD: physics.

SUBSTANCE: invention concerns equipment for registration of an ionising radiation flux of a unitary process of nano - and subnanosecond duration and can be used at registration of high-energy gammas at low fluence rate. The technical result in the Cherenkov's detector for registration of gamma emission impulses of nano - and subnanosecond duration, containing a converter (γ,e), a gas radiator, a rotary mirror and a light-receiving element, is reached because the light-receiving element of avalanche type, with the time resolution ~ 0.1 nc, not dependent on its photoresponsive area, is mounted after the rotary mirror, and the photoresponsive area S_pa of the avalanche type light-receiving element corresponds to the area of a cross section of the gas radiator S_rad., i.e. S_pa. ~ S_rad, electrical leads of the avalanche type light-receiving element are connected to the multichannel time analyser through a cable, and also that the light-receiving element of avalanche type is executed in a kind of the gas-filled spark counter containing mixed gas (C₂H₂F₄+10%SF₆) in gas volume, from a light source a translucent grid, a dielectric plate from glass with the photocathode (CsJ) placed on it, and a metal anode.

EFFECT: increase of Cherenkov's detector sensitivity.
