Absolute fission rates measurements in Mol-ΣΣ
Creators
Description
Absolute fission rate measurements were performed in the Mol-ΣΣ Secondary Standard Neutron Facility in order to prepare for subsequent high-fluence ILRR activation foil irradiations. Twelve separate chamber exposures were carried out from mid-1974 through early 1975. Fission cross section ratios based on these runs are (1.000: 1.173 +- 0.025: 0.0564 +- 0.0014: 0.381 +- 0.011) for 235U: 239Pu: 238U: 237Np respectively. The run-to-run fluence monitoring system--In(n,n') activation detectors and peripheral fission chambers--were established to a precision of +-0.4%
