Abstract:

In order to calculate absolute efficiency of the BF3 detector, MCNP/4C code is applied to calculate relative efficiency of the BF3 detector first, and then absolute efficiency is figured out through mathematical techniques. Finally an energy response curve of the BF3 detector for 1~20 MeV neutrons is derived. It turns out that efficiency of BF3 detector are relatively uniform for 2~16 MeV neutrons.

Key words: BF3 detector, Absolute efficiency, Relative efficiency, Energy response curve
