Development of μ-PIC with resistive cathode

The Micro Pixel Chamber (μ-PIC) using resistive Kapton on the cathode electrodes was developed and tested. The cathode electrodes were covered with resistive foil. Discharge problems are expected to be reduced due to spontaneous electric field reduction around the electrodes only for large electron deposit. The first prototype of this detector was made and tested. The gas gain more than 6000 was observed.
