AbstractAbstract
[en] The performance of wax neutron howitzers has been studied using a 200 mCi Am-Be neutron source. A smaller mouth diameter produces a greater thermal to epithermal ratio, and a higher thermal flux close to the source; however, small mouth diameters also produce large gradients in thermal neutron flux. Incorporation of metals such as brass, steel and lead into wax howitzers did not materially increase the thermal neutron output. (Auth.)
