| abstract | 1,262,937. Detecting neutrons. COMMISSARIAT A L'ENERGIE ATOMIQUE. 18 April, 1969 [18 April, 1968], No. 20017/69. Heading G6P. In a crystal analysis system a pencil of neutrons is diffracted by the test material and the space distribution of the resultant beams is detected by an ionization chamber employing boron tetrafluoride, boron trichloride or helium 3. The chamber comprises the fluid tight enclosure, 10, of a material having a small neutroncapture cross-section. N x n detector cells are formed in 10, by the mutually orthogonal n cathodes, 16, and the N anodes, 18, the cells consisting of the gas-filled spaces within the intersections of the anode and cathode strips. A high D.C. voltage is applied between the anodes and cathodes and the anode pulses are counted in a coincidence circuit. Amplitude-discriminators reduce the recording of the same neutron event by a plurality of adjacent cells. In an alternative form, an azimuthal scan of the neutron beam distribution is effected by an arcuate chamber 10 in which a number of vertical strip anodes are associated with a single curved cathode. |
