A MODIFIED PILE OSCILLATOR FOR THERMAL NEUTRON CROSS SECTION MEASUREMENTS

Journal Article · · Research Reactor J.
OSTI ID:4828979
A modified pile oscillator designed and constructed at the Battelle Research Reactor is described. This device cycles a material whose cross section is being measured through an annular neutron-sensitive ion chamber imbedded in the thermal column of the reaetor. The amplitude of the signal from the ion chamber generated by neutron absorption in the sample while passing through the chamber is indicative of the thermal neutron absorption cross section. Direct comparison of this amplitude with the amplitude of signal generated by a standard of known cross section determines the thermal neutron absorption cross section of the unknown sample. (N.W.R.)
