TOTAL ABSORPTION DETECTOR Russian patent published in 1994 - IPC

FIELD: technical physics. SUBSTANCE: total absorption detector has coincidence member, cesium iodate crystal connected with the first photomultiplier which generated pulse signal used for amplitude analysis. The second photomultiplier, light filter, delay unit, are brought into the device additionally. Light filter is placed between crystal and the second photomultiplier which has output connected with the second input of coincidence member through delay unit. Crystal is made activator-free, light filter doesn't transmit UV range of light radiation. EFFECT: improved speed of operation. 2 dwg
