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.
