标题： Detection of Alpha Particles and Low Energy Gamma Rays by Thermo-Bonded Micromegas in Xenon Gas

摘要： 微米巨块是一种目前正在研发的微型图案气体探测器，适用于稀有事件搜索实验。 此处我们报告了一种由微网通过热压结合到读出平面的微米巨块结构的性能，这是由于其在两相氙探测器中用于暗物质和无中微子双β衰变实验的潜在应用。 该研究是在室温下的纯氙气中进行的。 使用镅-241源的α粒子测量显示，在氙气压力高达3大气压时可以获得大于200的气体增益。 该装置观察到了低至8 keV的伽马射线。 显示英文摘要

摘要： Micromegas is a type of micro-pattern gaseous detector currently under R&D for applications in rare event search experiments. Here we report the performance of a Micromegas structure constructed with a micromesh thermo-bonded to a readout plane, motivated by its potential application in two-phase xenon detectors for dark matter and neutrinoless double beta decay experiments. The study is carried out in pure xenon at room temperature. Measurements with alpha particles from the Americium-241 source showed that gas gains larger than 200 can be obtained at xenon pressure up to 3 atm. Gamma rays down to 8 keV were observed with such a device.
