Measurement of the neutron fluence on the spallation source at Dubna

Original language description

A Th-232 activation sample was exposed directly to the spallation neutrons produced by 1 GeV proton colliding with a lead target and other samples of Au-197, Bi-209, Co-59, In-115 and Ta-181 were irradiated by moderated neutrons after passing through 6 cm of paraffin. Different (n, ?) and (n, xn) reaction products in Th-232, Au-197 and Bi-209 samples are analyzed by gamma-ray spectrometry to measure the neutron fluence at the positions of the samples. For this purpose a histogram of 'flat' spectrum averaged neutron cross-sections in over thirty given energy groups was determined from the PREPRO-2000 software. Results of measurements are compared with Monte-Carlo simulations by the Dubna CASCADE code. Experimental values for both spallation and moderated neutron fluences are in reasonable agreement with the CASCADE code.

Czech description

Masivní olověný terč jsme ozařovali protony s energií 1 GeV, ve kterém se produkovaly neutrony. Měřením výtěžků reakcí (n,gamma) a (n,xn) na 232Th, 209Bi a 197Au jsme stanovili tok neutronů dopadající na tyto terče.
