Abstract

Measurements are performed of the density of photoneutron fluxes from cylindrical targets of2H2O (diameter 64 and height 86 mm), Be (outer diameter 70, inner diameter 40, height 100mm), and238U (diameter 44.5 mm, height 50 mm) under the action of braking radiation from electrons with energies of 4 to 8 MeV in order to determine the effect of target form and orientation relative to the detector upon the recorded photoneutron level. The fluxes were measured by an "all-wave" neutron detector based on an SNM-11 counter in a paraffin retarder at an angle of 90‡ to the axis of the braking radiation beam for various target orientations relative to the detector. Measurement results are compared to calculations. Photoneutron fluxes from heavy water and beryllium targets of the indicated dimensions were also measured for angles of 90, 135, and 167‡. An isotropic nature was noted in the photoneutron fluxes from both targets.
