摘要：

Thermal neutron flux monitors were fabricated using chemical vapor deposited single crystal diamond in a p-type/intrinsic/metal/(LiF)-Li-6 layered structure. They were placed 80 cm above the core midplane of a 1 MW research fission reactor, where the maximum neutron flux is 2.2x10(9) neutrons/cm(2) s. Good stability and reproducibility of the device response were observed over the whole reactor power range. A 150 000 counts/s count rate was measured at the maximum reactor power with no degradation of the detector signal. As the multiple pile-up process due to the slow readout electronics is accounted for, an excellent linearity of the diamond response is observed. (c) 2007 American Institute of Physics.
