Promising Neutron Detector with Anticoincidence Protection
Mitrofanov, I. G.; Litvak, M. L.; Sanin, A. B. +6 more
The method of remote neutron and gamma spectrometry of bodies in the solar system (the Moon, Mars, and Mercury) has been used for several decades to estimate the nuclear composition of these objects and the hydrogen abundance in their subsurface layers. Proportional gas counters based on helium-3 (3He), which have the maximum efficiency…
Comparison of Sensitivities of Semiconductor (HPGe) and Scintillation (CeBr3) Detectors in the Measurement of Gamma Spectra Induced by Neutrons in the Model of Planetary Soil
Mitrofanov, I. G.; Golovin, D. V.; Kozyrev, A. S. +12 more
The results of neutron-activation measurements performed using the model of planetary soil and detectors based on high-purity germanium (HPGe) and cerium bromide (CeBr3) are reported. Gamma lines lying in the energy range from 200 keV to 8 MeV are used as indicators to compare these two types of detectors in experiments with the model i…
