Effects of nuclear fusion produced neutrons on silicon semiconductor plasma X-ray detectors

Investigation of X-ray spectral response of D-T fusion produced neutron irradiated PIPS detectors for plasma X-ray diagnostics

“…The authors observed the continuous operation of radiation shielded detectors till the neutron fluence of 5.34 × 10 10 n/cm 2 (after the D-T phase) and extended operation until 1.5 × 10 12 n/cm 2 was anticipated. Kohagura et al [10][11][12] investigated the nuclear fusion produced neutron irradiation induced deterioration in the X-ray energy response of silicon detectors up to a neutron fluence of 10 15 n/cm 2 . In all the above reports, the detectors were operated in current-mode.…”
