我们正在开发一个中子束监测器与气体电子倍增器（GEM）的高强度全衍射仪在J-PARC。为了分析基于GEM的探测器的基本特性，在J-PARC进行了中子辐照试验。实验得到的波长-光谱分布与计算结果一致，光束轮廓与简单的蒙特卡罗（MC）模拟结果一致。基于GEM的探测器的位置分辨率估计为约1.2mm。因此，我们发现，作为一个中子束监测器，基于GEM的探测器具有良好的二维成像能力。
We are developing a neutron beam monitor with a gas electron multiplier (GEM) for the high-intensity total diffractometer at J-PARC. In order to analyze the basic characteristics of the GEM-based detector, a neutron irradiation test was carried out at J-PARC. The wavelength-spectrum distribution obtained from the test is consistent with the calculations, and the beam profiles agree with the simple Monte Carlo (MC) simulation. The position resolution of the GEM-based detector is estimated to be approximately 1.2mm. Therefore we found that as a neutron beam monitor, the GEM-based detector has good two-dimensional imaging ability.
