Abstract

Diamond PIN diodes with an approximately 5-μm thick i-layer and coated with a thin boron nitride (BN) layer have been tested with a thermal neutron beam. For a flux of 4.4 × 10⁶ n/s/cm², count rates were on the order of 30–100 counts per second depending on the thickness of the BN neutron converter layer. Pulse height spectra showed features associated with α and ⁷Li fission products consistent with the thickness of the BN layer. An irradiation test with a 1 MeV neutron equivalent fluence of 10¹⁵ n/cm² showed no significant alteration in the count rate of the tested detector.
