STATEMENT OF WORK
RADIATION IMAGING DETECTOR SYSTEM
7 JANUARY 2020
GENERAL
The Air Force Institute of Technology (AFIT) located at Wright Patterson Air Force Base is in need of a radiation imaging (localization) detector System that will enable research to measure the distribution of ionizing radiation from a weak orphan source in a field of background radiation.
The dual back-to-back solid state radiation detectors shall be capable of resolving the direction of a radiation source and simultaneously determining the type of source using spectroscopy. AFIT research will ultimately enable rapid and efficient detection and identification of nuclear weapons and nuclear debris in the field on mobile platforms. The proposed experimental radiation imaging detector system has the capability of being a frontrunner technology to revolutionize field radiation imaging.
The following specification lists the minimum (threshold) requirements.
1. The system shall be composed of two parallel Segmented Planar double sided strip detectors
(DSSDs) made using high purity germanium (HPGe). This dual planar HPGe strip detector system shall be electrically cooled and have a front scatterer detector with minimum dimensions of 40x40x10 millimeters with 10X-10Y (10 charge collecting strips on both sides) and a back absorber detector of minimum dimensions 40x40x20 millimeters with 10X-10Y
(10 charge collecting strips on both sides).
2. Detectors shall be electrically cryo-cooled by oil-free, maintenance free, helium cryo-cooler(s) including high-voltage inhibit power and signal cables.
3. Electrically cooled detectors shall be capable of efficient charge collection at high gamma energies. Measured energy resolution required is less than or equal to 2.2 keV at 514 keV on each strip.
4. Detectors shall be capable of gamma measurement energy range between at least 3 keV and 2
MeV.
5. Detectors shall be capable of providing transient signals for sub-pixel X-Y spatial resolution.
6. Detectors shall be capable of warming without energy resolution degradation.
7. Electronics shall include preamplifiers, alarm card, and HV filtering network.
8. Low noise preamplifiers shall be provided for charge collection and signal processing for each detector strip.
9. Detector enclosures and signal cables shall be designed for maximum EMI rejection.
10. Electrical cooling shall enable efficient charge collection at high gamma energies. Measured energy resolution shall be less than or equal to 2.2 keV at 514 keV on each strip.
