HODOSCOPE Russian patent published in 2007 - IPC G01T3/06 G01T1/20 

FIELD: analysis of materials through detection of their physical properties, in particular, research and analysis of objects by radiation methods to detect radioactive materials and sources.

SUBSTANCE: claimed hodoscope contains a block of hydrogen-containing scintillating optical elements, placed in rows in turns in two mutually perpendicular directions, and photo-detectors. Scintillating optical elements are made in form of rods with rectangular cross-section covered by light-reflective cover, at least on one side of each rod grooves are made, scintillating fibers are positioned in grooves, on fiber ends photo-diodes are positioned, at least one side of packet is serially covered by two pairs of plates for registration of heat neutrons and for registration of gamma quanta, each pair is divided by additional plates made of substances which weaken corresponding types of radiations, photo-diodes and pairs of plates for registering heat neutrons and for registering gamma quanta are connected to inputs of coincidence circuits, outputs of which are connected to inputs of controller, and outputs of controller are connected to input of computer.

EFFECT: possible reaction to both fast neutrons and heat neutrons, and also to gamma and x-ray radiation; also it is possible to identify radiation and to determine direction towards the source of radiation.
