Study of narrow gas gap resistive plate chamber in the streamer mode
2004
Abstract The performances of a glass Resistive Plate Chamber (RPC), operated in the streamer mode, were measured for various gas gaps between 0.25 and 1.00 mm . Development of standard streamers requires ⩾0.75-mm gap. Below 0.4 mm , no signal streamer was observed. For the 1.00 mm gap, time resolution was 0.65±0.03 ns with the 97.5% detection efficiency. For the 0.75 mm gap, they are 0.53±0.02 ns and 96.0%, respectively. For signal charge, the 0.75 mm gap had 25–30% smaller than the 1.00 mm gap and 70–75% smaller than the 2.00 mm gap.
