The imaging detectors using Micro Pattern Gas Detectors (MPGD) have been widely utilized considering characteristics of high tolerance to nuclear radiation, flexibility for many types of radiation, and compatibility for large-area detectors. The Gas Electron Multiplier (GEM) is a widely used MPGD due to its characteristics of high charge gain, generally high spatial resolution, and flexibility in the development of readout systems for GEM-based detectors. In this work, a Glass Gas Electron Multiplier (G-GEM) was developed using a photosensitive etchable glass (PEG3C) substrate. It has sensitive areas of 100 × 100 mm². The thickness, hole size, and hole pitch are 680 µm, 170 µm, and 280 µm respectively. A 100 × 100 mm² multichannel strip was developed and coupled with the G-GEM as the electrode readout anode. A signal readout consisting of charge sensitive preamplifier, CR-RC shaping amplifier, digitization system, and FPGA was developed. The characteristics of G-GEM, energy-solving performance, and preliminary results of the imaging system are presented in this work.
