The INEL beryllium multiplication experiment annual report FY89

Description

This is a report of activities during the second year of a three-year program to measure the multiplication of 14-MeV neutrons in bulk beryllium. The operating parameters of the neutron generator were established. The manganese sulfate solution was chemically characterized. A 252Cf neutron source was acquired for use in studying the systematics of the experimental setup. Measurements were made of the multiplication of neutrons in beryllium, using both 14-MeV neutrons and the 252Cf source. Uncorrected multiplication values for the 14-MeV neutrons are 2.110, 1.927, and 1.388 for the 19.9 cm, 12.1 cm, and 4.6 cm beryllium thicknesses, respectively. A preliminary Monte Carlo calculation, using MCNP, predicts a value of 2.125 for the uncorrected value of neutron multiplication for the 19.9 cm sample in the manganese bath. The ratio of calculation to experiment is 1.007, supporting the validity of the microscopic cross section files. 13 refs., 4 figs., 3 tabs
