Paper Abstract

Existing neutron imaging detectors have limited count rates due to inherent property and electronic limitations. The popular multiwire proportional counter is qualified by gas recombination to a count rate of less than 105 n/s over the entire array and the neutron Anger camera, even though improved with new fiber optic encoding methods, can only achieve 106 cps over a limited array. We present a preliminary design for a new type of neutron imaging detector with a resolution of 2 - 5 mm and a count rate capability of 106 cps per pixel element. We propose to combine optical and electronic processing to economically increase the throughput of advanced detector systems while simplifying computing requirements. By placing a scintillator screen ahead of an optical image processor followed by a detector array, a high throughput imaging detector may be constructed.
