A 3-dimentional tracking detector for a high-counting rate experiment at J-PARC was developed. To use the detector in the high-counting rate environment, Micro Pixel Chamber (mu-PIC) was used for a readout pad. The vacuum chamber for installing mu-PIC and the drift cage which is an upper part were designed. Two GEM pad is installed above mu-PIC for obtaining high gain. By using a P10 gas and applying a proper high-voltage, we obtained a gain of 4th power of 10. The operation and signal reading of the detector was tested by the cosmic-ray. From the readout board of mu-PIC, we checked 10-microsec delayed signals which were generated by the cosmic-ray passing though the detector. From several testes, we expected to obtain the required performance.

本文介绍了一种用于日本PARC高计数率实验的三维跟踪探测器。为了在高计数率环境中使用探测器，微像素室（μ-PIC）被用作读出垫。设计了用于安装μ PIC的真空室和上部漂移笼。两个GEM焊盘安装在mu-PIC上方以获得高增益。通过使用P10气体并施加适当的高压，我们获得了10的4次方的增益。利用宇宙射线对探测器的工作和信号阅读进行了测试。在μ PIC的读出板上，我们检测了宇宙射线通过μ PIC探测器产生的10微秒延迟信号。通过多次测试，我们期望获得所需的性能。
