Abstract

Abstract:

Fourteen MeV pulsed neutron irradiated coal sample of certain thickness was simulated with the aid of MCNP5 package. Inelastic and capture γ spectra were acquired by controlling the tally time. Collection location of γ spectra is determined by count rates. Trends of inelastic and capture γ spectra of coal samples with different thickness were observed.

Key words: prompt gamma neutron activation analysis (PGNAA）, capture, coal sample thickness, &gamma, spectra

CLC Number:
