基于双面印刷电路板（PCB）技术，开发了一种用于x射线、伽马射线和带电粒子成像的气体探测器“微像素室（μ-PIC）”。测试了x射线和带电粒子的成像特性。作为x射线探测器，获得的位置分辨率为160 μm (RMS)，图像均匀度在24%以内。此外，作为带电粒子探测器，三维分辨率达到260 μm。然而，气体增益不足以探测最小电离粒子的轨迹。为了提高气体增益，我们提出了一种新的电极结构，采用新的制造技术。仿真结果表明，期望的采集效率比现有的μ-PICs提高3倍。
A gaseous detector “Micro Pixel Chamber (μ-PIC)” based on double-sided Printed Circuit Board (PCB) technology has been developed for X-ray, gamma-ray, and charged particle imagings. Imaging properties for X-ray and charged particles were tested. As a X-ray detector, achieved position resolution was 160 μm (RMS), and the image uniformity within 24% was obtained. Furthermore, three-dimensional resolution of 260 μm were obtained as a charged particle detector. However, the gas gain is not enough to detect the tracks of minimum ionizing particles. In order to improve the gas gain, we proposed a new electrode structure using a new manufacture technology. According to a simulation, the expected collection efficiency is three times higher than the current μ-PICs.
