Abstract

In order to meet the ground calibration requirements of Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) satellite gamma ray detector (GRD), two sets of single-energy x-ray calibration devices were established in China Metrology Institute (Changping). One set is a single crystal calibration device, and LiF crystal can realize continuous emission of (8.1-37.9) keV single-energy X-ray; The other set is a dual crystal calibration device. Si220 crystal and Si551 crystal can realize continuous light emission of single energy x-ray in the energy range of (38-160) keV. The X-ray energy spectrum, energy resolution and energy response of the calibration device were studied by standard high-purity germanium detectors. The test results show that the energy range of the calibration device is: (8-160) keV; monochromaticity: energy resolution 3.1%@8.1keV, 10.2%@79.9keV; monochromatic luminous flux 649cts/s@38. 0keV,678cts/s@79.9keV,298cts/s@121.8keV; monochromatic light ratio 96%@38.0keV, 97%@79.9keV, 96%@121.8keV. Combined with the actual test results of the energy point of the GRD, it indicates that the calibration device can meet the calibration requirements of the GRD.

GECAM卫星伽玛射线探测器标定装置研究

为满足引力波高能电磁对应物全天监测(GECAM)卫星伽马射线探测器(GRD)地面标定要求，在中国计量科学研究院(昌平)建立了两套单能x射线标定装置。一套为单晶校准装置，liff晶体可实现连续发射(8.1-37.9)keV单能x射线;另一套是双晶校准装置。Si220晶体和Si551晶体可以实现(38-160)keV能量范围内单能量x射线的连续发光。采用标准高纯锗探测器对标定装置的x射线能谱、能量分辨率和能量响应进行了研究。试验结果表明，该标定装置的能量范围为:(8 ~ 160)keV;单色性:能量分辨率3.1%@8.1keV, 10.2%@79.9keV;单色光通量649cts/s@38。678年0 kev cts / s@79.9keV, 298 cts / s@121.8keV;单色光比96%@38.0keV, 97%@79.9keV, 96%@121.8keV。结合GRD能量点的实际测试结果，表明该标定装置能够满足GRD的标定要求。
