A pixilated anode design of a high pressure xenon gamma-ray spectrometer is investigated. This design is composed of a single planar cathode and four anode pixels embedded in the center of a "non-collecting" anode plate. This design removes the Frisch grid which can suffer from excessive micro-phonics in real-world applications. To investigate the energy resolution of this design, the charge collecting efficiency and waveform of induced charge on each anode were calculated via tracking electron cloud drifting.
