新型气体探测器“微像素室（μ-PIC）”专为X射线、伽马射线和带电粒子成像而开发。 μ-PIC基于双面印刷电路板制成，可以轻松生产大尺寸探测器。使用间距为0.4mm的3cm×3cmμ-PIC成功地进行了操作测试。在这些测试中测量了气体增益和稳定性。增益为103，连续工作5天，阳极和阴极之间既没有增益降低，也没有放电。此外，在高达 107cps（每秒计数）/mm2 的强 X 射线照射下，没有观察到增益下降。
The novel gaseous detector “Micro Pixel Chamber (μ-PIC)” has been developed for X-ray, gamma-ray and charged particle imaging. The μ-PIC is made based on a double-sided printing circuit board, by which a large size detector could be produced easily. The operation tests were performed successfully using a 3 cm ×3 cm μ -PIC with a 0.4 mm pitch. The gas gain and stability were measured in these tests. There is neither gain reduction nor discharge between anode and cathode at a gain of 103for 5 days continuous operation. Also, no gain decrease was observed up to 107cps(counts per second)/mm2intense X-ray irradiation.
