Abstract : We report development of a Radiation Hard Sensor for Surveillance. The sensor is being developed by Applied Research Corporation, under an SBIR program. The sensor is based on a Superheated Superconducting Colloid Detector (SSCD). Detection of X-rays, gamma-rays and neutrons is monitored by superconducting quantum interference devices (SQUID). Considerable progress has been made in demonstrating that high spatial resolution is possible, and especially that these superconducting detectors are not sensitive to radiation damage up to 35 MRads. We have constructed high quality low noise amplifiers in order to take advantage of the SQUID sensitivity. Multichannel readout capability is presently being built.
