Abstract
We developed a novel design of a Micro Pixel Chamber (μ-PIC) with resistive electrodes for a charged particle tracking detector in high rate applications. Diamond Like Carbon (DLC) thin film is used for the cathodes. The resistivity can be controlled flexibly (10(5-7) Ω/sq.) with high uniformity. The fabrication process was greatly improved and the resistive μ-PIC could be operated with an area of 10 × 10cm(2). Resistors for the HV bias and capacitors for the AC coupling were completely removed by applying PCB and carbon sputtering techniques, and the resistive μ-PIC became a very compact detector. The performance of our new resistive μ-PIC was measured in various ways. Consequently, it was possible to attain high gas gains (>10(4)), high detection efficiency, and position resolution better than 100μm. The spark probability was reduced, and the new resistive μ-PIC was operated stably under fast neutrons irradiation. These features offer solutions for a charged particle tracking detector in future high rate applications.
