The new type of pulse neutron detector consists of two PIN detectors. The respon se for the rays was studied with the pulse gamma sources. The neutron respons e was studied using the DT neutron sources and compared with the scintillator de tector. Results show that the detector is insensitive to gamma radiation, and th e neutron sensitivity was determined by the neutron radiator. It is a new pulse neutron detector in the neutron and gamma mixed radiation fields.

Time- and space- resolved x-ray spectrum diagnostic system has been established by coupling flat-field grating and gated-MCP (micro-channel plate) with an optic al CCD. A series of experimental investigations on the characterization of the d iagnostic system have been carried out to develop quantitative measurement techn ology of x-ray absorption spectrum. This diagnostic technology has been successf ully applied to the measurements of absorption.
