Abstract

The influence of some experimental factors on the measured quantities in neutron spherical-shell transmission benchmark experiments was estimated by simulating the corresponding components of the set-up (materials near the neutron source, collimator and shield of the detector etc.) as well as the specific measuring technique (time-of-flight spectrometry) in Monte-Carlo calculations. The calculations were performed by the MCNP code with nuclear data from the EFF-1 and FENDL-1 libraries. The corrections describing the effects of several distinct experimental details were evaluated.

Keywords
