| Outline of Final Research Achievements |
We have been developing gamma-ray detectors relying on superconducting resonators. Since these detectors can be largely multiplexed and show potential for quick response time, high spatial resolution, and high energy resolution, the proposed detectors could be suitable for use as food-screening systems.
The superconducting resonators were fabricated with a niobium on a silicon wafer. We demonstrated 96 pixel arrays on a 20mm by 12 mm chip. The detectors were coupled to a 2-mm-thick lead absorber. We operated them in a 0.3 K cryostat and examined their characteristics against gamma-rays radiated from a cesium 137 source. We found that the detectors’ response time was around 3.6 micro second and the detector had the energy resolution of 3.8 keV at 662 keV.
