摘要:

与宇宙射线的相互作用是限制未来空间飞行任务中测辐射热探测器灵敏度的一个重要现象。我们使用来自放射源的伽马射线和来自X射线管的X射线测试了冷电子测辐射热计(CEB)对电离辐射的灵敏度。我们描述了测试设置和结果。正如预期的那样,由于传感元件的有效隔热和其可忽略的体积,我们发现CEB在很大程度上不受这个问题的影响。

英文摘要:

An important phenomenon limiting the sensitivity of bolometric detectors for future space missions is the interaction with cosmic rays. We tested the sensitivity of Cold Electron Bolometers (CEBs) to ionizing radiation using gamma-rays from a radioactive source and X-rays from a X-ray tube. We describe the test setup and the results. As expected, due to the effective thermal insulation of the sensing element and its negligible volume, we find that CEBs are largely immune to this problem.
