Title:
LABELLED NEUTRON GENERATOR
Document Type and Number:
WIPO Patent Application WO/2004/029601
Kind Code:
A1
Abstract:
The invention relates to devices for producing labelled neutron beams, in particular to sealed neutron generators and can be used for systems for an operative non-destructive remote analysis of complex chemical substances. The aim of the invention is to combine a sealed neutron generator and a multichannel $g(a) detector in order to form a single system. The sealed body (1) of the inventive generator comprises an ion source (2), a gaseous deuterium and tritium source (3), accelerating and focusing electrodes, a tritium target and a compact matrix of scintillators (6) which are provided with scattered deuteron absorbers (8). The photomultiplyers of the $g(a) detector are arranged on the external side of the generator body and connected to the scintillators through glass windows (7). The interaction reaction of accelerated deuterons with the tritium target produces monochromatic $g(a) particles and neutrons. The particle $g(a) recording is carried out by one of the scintillators which are arranged in the space in a determined manner, and makes it possible to define the direction and the moment of emission of each neutron from the target ( label it). The scintillators $g(a) are embodied in the form of non-organic yttrium aluminate crystals which are activated with cerium (Y Al O3-YAP (Ce)). Said invention makes it possible to increase the working life of the neutron generator by preserving a static vacuum in the sealed body thereof and to increase the space-time resolution of the device
