Process and device for flow control of fissionable material and determination of the burn-up of core elements by neutral coincidence measurement
Description
The use of a time-amplitude converter, to which the signals from two neutron detectors situated around a source are taken, is proposed. The output signals of the time amplitude converter are analysed in a multichannel analyser and are shown on a VDU screen, for example. Coincident fission neutrons lead to a peak in the spectrum produced, whose nett area is a measure of the quantity of fissionable material of the source. (orig./HP)

Es wird die Verwendung eines Zeit-Amplitudenkonverters, dem die Signale von zwei um eine Quelle angeordneten Neutronendetektoren zugeleitet werden, vorgeschlagen. Die Ausgangssignale des Zeitamplitudenkonverters werden von einem Vielkanalanalysator analysiert und beispielsweise auf einem Bildschirm sichtbar gemacht. Koinzidente Spaltneutronen fuehren zu einem Peak in dem entstehenden Spektrum, dessen Netto-Flaeche ein Mass fuer die Menge spaltbaren Materials in der Quelle ist. (orig./HP)Additional details
