Here we have developed an innovative scintillation gamma-ray detector using liquid xenon to prompt epoch-making progress in the fields of fundamental science where precise measurements of gamma-rays with energies of hundreds of keV to tens of MeV are essential. After successful developments of photomultipliers that are sensitive to ultraviolet scintillation light of xenon (a wavelength of 178nm) under liquid xenon temperature (-lOOC), a pulse tube refrigerator that works efficiently at liquid xenon temperature, and a liquid xenon purification system to remove a small contamination to absorb the ultraviolet light, a 100-liter detector was build and subjected to various performance tests. A stable, long-term operation was established. Using high energy gamma-rays from laser Compton scatterings at an electron storage ring, its excellent resolutions in energy time, and position of gamma-rays were successfully demonstrated. Application of this detector to PET also seems promising. A further development for higher energies is expected.

在这里，我们开发了一种使用液体氙的创新闪烁伽马射线探测器，以促进基础科学领域的划时代进展，其中精确测量能量为数百keV至数十MeV的伽马射线至关重要。在成功地研制出在液态氙温度（-100 ℃）下对氙的紫外闪烁光（波长为178 nm）敏感的光电倍增管、在液态氙温度下有效工作的脉冲管制冷机以及去除少量污染物以吸收紫外光的液态氙净化系统之后，构建了100升探测器并进行了各种性能测试。建立了长期稳定的业务。利用电子储存环上的激光康普顿散射产生的高能γ射线，成功地证明了它在能量、时间和γ射线位置方面的优良分辨率。这种探测器在PET上的应用也很有前景。预计更高能量的进一步发展。
