We previously succeeded in constructing and demonstrating the capability of a neutron imaging system based on a superconducting current-biased kinetic inductance detector (CB-KID). In the present work, we systematically studied the characteristics of the superconducting neutron detector to improve the spatial resolution and detection efficiency. We found that the number of neutron detection events with CB-KID remarkably increased when the detector temperature increased from 4 K to the critical temperature T c . We observed systematic changes of neutron signals as a function of the detector temperature from 4 K to T c . We evaluated the detection efficiency of the CB-KID detector, and compared with PHITS Monte Carlo simulations, which modeled the sequential physical processes for the 10 B(n,α) 7 Li reaction, the transport dynamics, and the energy deposition by particles including neutrons, 4 He particles, 7 Li particles, photons, and electrons.
