  • Abstract: A novel Micro-Pattern Gaseous Detector (MPGD) Micro-Mesh Micro-Pixel Chamber ( Formula Not Shown -PIC) has been developed for particle imaging and/or a TPC readout. The Formula Not Shown -PIC consists of a micro-pixel chamber ( Formula Not Shown -PIC) and a thin micro-mesh film. An intensive electric field is formed around a point-like anode electrode that provides higher gas gain and more stable operation than existing MPGDs. In addition, ion backflow fraction (IBF) into the detection volume is strongly suppressed. A prototype of this detector ( Formula Not Shown ) has been manufactured and successfully operated. Stable operation with a gas gain of more than Formula Not Shown was achieved using an Formula Not Shown gas mixture, and the measured IBF was 0.5%.
