The three grids define three critical regions: 1. The buffer region:a 10 cm buffer region that serves to degrade the high voltage set on the cathode to the grounded PMT-energy plane. The thickness of this region is set to establish a suitable reduced electric field, avoiding unwanted electroluminescence and mitigating neutral bremsstrahlung emission in this region [19]. 2. The drift region:a 30 cm long volume between the cathode and the gate, where a moderate reduced electric field ( ∼50 V/cm/bar) drifts ionization electrons. The field in this region is generated by the cathode-gate voltage difference, and is degraded along the field cage using metallic rings connected by resistors. The cathode consists of a grid of 15 parallel wires stretched over
