Monte Carlo Study on Gas Pressure Response of He-3 Tube in Neutron Porosity Logging
Thermal neutrons are detected by (n,p) reaction of Helium-3 tube in the compensated neutron logging. The helium gas pressure in the counting area influences neutron detection efficiency greatly, and then it is an important parameter for neutron porosity measurement accuracy. The variation law of cou...
