Abstract

1,226,928. Detecting neutrons. THOMSONC.S.F. 26 Feb., 1970 [4 March, 1969], No. 9462/70 Heading G6P. In a neutrongraphical system, a moderator interposed between the neutron source and the object under investigation produces gamma radiation, the parasitic image effect of which on the viewing device is reduced by the interposition of a shutter at the viewing device which opens after the incidence of the gamma radiation. The neutrons, having a low energy after moderation, arrive at the viewing device after the radiation. The shutter may be a rotating apertured disc, a Kerr cell, an electronic shutter or ring electrode in a neutron-electron converter tube.
