Measurement of the 2. 35 MeV window in O + n

PDF Version Also Available for Download.

Description

Calculations are made showing that the ion temperature of a deuterium plasma with a Maxwellian distribution can be found by measuring the transmission of the d-d neutrons through liquid oxygen. The method is useful for temperatures up to 6 keV. It does not depend on the absolute neutron yield but does require accurate total neutron cross sections for oxygen. In this experiment the cross section of natural oxygen was measured from 2.0 to 3.0 by neutron time-of-flight at the Oak Ridge Electron Linear Accelerator (ORELA). The fitted cross sections have a 110.9 +- 1.7 mb minimum at 2351.5 keV.
