摘要：

In this paper we propose a method of fast neutron flux estimation from a pulsed D-T neutron generator with application of single CaF2 scintillation crystal. The analysis method relies on F-19(n, alpha)N-16 threshold activation reaction having neutron energy threshold at 1.6 MeV. As a result, the N-16 undergo beta(-) decay with half-life of 7.1 s, emitting beta particles with endpoint up to 10.4 MeV in the scintillator medium. Integration of the beta distribution curve, preceded by calculation of (n, alpha) rate on F with Monte Carlo N-Particle Transport Code v6 (MCNP6) for fixed geometry, allows to estimate the neutron flux in 4 pi per second within few minutes.
