文摘

Geant4 study of a neutron detector with three 3He orthogonal tubes inside a HDPE sphere. Geant4 physics models are adequate to characterise this detector. Result: The 3He tube efficiency changes significantly with respect to position along the tube length. Indications on how to further investigate and asses the suitability of this detector.
