Webb12 apr. 2024 · We developed a cosmic-ray neutron sensing probe (CRNP) for this study using a proportional counter tube filled with BF 3, which can detect neutrons in the fast energy range. The fast neutron is absorbed while passing through the tube and induces a pulse of electrical current that is sent to the pulse module. Webb17 juli 2013 · The neutron probe is relatively easy to use, accurate, and capable of measurements in real time. A probe with a fast neutron source is placed on the surface or lowered in an access tube (transparent to the neutrons), and the back-scattered slow neutrons are measured.
