在这项研究中,我们提出并演示了一种新颖的成像系统,即气体平板探测器(FPD)。气态 FPD 由带有闪烁气体的玻璃气体电子倍增器 (G-GEM) 组成,与采用液晶显示技术制造的光电二极管面板进行光学耦合。 G-GEM 是理想的低能量沉积辐射探测器,因为它具有单级高气体增益,因此具有高光子产率。我们使用 Ne/CF490/10 气体混合物通过系统获得了初步 X 射线图像。 FWHM 中的典型位置分辨率为 0.93 毫米,这是通过边缘轮廓拟合获得的
In this study, we propose and demonstrate a novel imaging system, a gaseous flat-panel detector (FPD). The gaseous FPD consists of a glass gas electron multiplier (G-GEM) with a scintillation gas, which is optically coupled with photodiode panel fabricated with liquid crystal display technology. The G-GEM is ideal as a low energy deposition radiation detector because of its single stage high gas-gain and hence, its high photon yield. We obtained a preliminary X-ray image with the system by using a Ne/CF490/10 gas mixture. The typical position resolution was 0.93 mm in FWHM, which was obtained from the fitting of edge profiles
