Development of self-powered neutron detectors for neutron flux monitoring in HCLL and HCPB ITER-TBM

, 2014
Self powered neutron detectors (SPND) have a number of interesting properties (e.g. small dimensions, capability to operate in harsh environments, absence of external bias), so they are attractive neutron monitors for TBM in ITER.
