Photoneutron Source for the Pile G1; SOURCE DE PHOTONEUTRONS
Technical Report
·
OSTI ID:4333332
An antimony-beryllium neutron source has been developed which ensures for the pile G 1 (neutron production by gamma ,n reaction), one month after a shut-down following a long run at 40 Mw, a flux at the center high enough to be detected without difficulty by the starting-up ionization chambers. ln fact, measurements show that this source produces a flux, at the center, of 1.4 x 10/ sup 6/ n/cm/sup 2//sec that is, a power of 9.1 watts, in the case where the antireactivity is 1,600 pcm. The corresponding reading on the ionization chambers is 85 mv. The effect of the source on the reactivity of the pile is interpreted by an absorption of 25 pcm. The saturation activity to the antimony at a power W of 40 Mw would be 2000 curies. There is no danger of over-heating of the source in the course of a run at high power. (auth)
