Abstract

Under NASA sponsorship, the authors are developing a solid-state neutron sensor capable of being incorporated into a very compact flight instrument to provide high-quality real-time measurement of this important radiation flux. The dosimeter uses a special, high neutron sensitivity PIN diode that is insensitive to the other forms of ionizing radiation. The dosimeter will have the ability to measure and record neutron dose over a range of 50 microgray to tens of milligrays over a flight of up to 30 days. The performance characteristics of the PIN diode with a detailed description of the overall dosimeter is presented
