WebENMC's higher efficiency and shorter die-away time leads to dramatic reductions in counting time. At an α value of 1, the ENMC is about 10 times faster than a thermal neutron … Web11 de fev. de 1999 · This study has resulted in the development of a new dual-range 3 He neutron proportional counter design for use in high gamma-ray environments. The new tube design employs low- Z tube wall materials to minimize gamma-ray interactions, a low- Z quench gas which is not prone to radiative disassociation, and a 10 B tube lining.
