本文介绍了一种微量热γ射线探测器，它对103keV光子的能量分辨率为42eV。该探测器由绝热超导过渡边温度计和超导体锡光子吸收器组成。吸收器与生产高分辨率γ射线探测器阵列的技术兼容。详细表征的检测器，其中包括测量的复阻抗，检测器噪声和时域脉冲响应的结果表明，更深入地了解和优化的吸收体和温度计之间的热传输可以显着提高未来的探测器的能量分辨率。
The authors describe a microcalorimeter γ-ray detector with measured energy resolution of 42eV full width at half maximum for 103keV photons. This detector consists of a thermally isolated superconducting transition-edge thermometer and a superconducting bulk tin photon absorber. The absorber is attached with a technique compatible with producing arrays of high-resolution γ-ray detectors. The results of a detailed characterization of the detector, which includes measurements of the complex impedance, detector noise, and time-domain pulse response, suggest that a deeper understanding and optimization of the thermal transport between the absorber and thermometer could significantly improve the energy resolution of future detectors.
