Abstract
Lunar water ice is an important resource to support the
construction of lunar base and other deep space activities, and it
is crucial to detect lunar water ice. In this paper, we studied the
detection of lunar water ice based on a small neutron generator
through Monte-Carlo simulation. The schematic of the detection
system and the principle are explained. The simulation results
demonstrate that the change of thermal neutron flux with the
increase of water content is most obvious and clear. There is a
positive correlation between thermal neutron counting and water
content in lunar soil. Using thermal neutron counting, the water
content can be obtained by inversion.
