Charge properties in glass-electrode resistive plate counters

We have measured the charge response to single cosmic-ray muons passing through a glass-electrode resistive plate counter under several different operating conditions. Under appropriate conditions, we find that the width of the charge response is better than measured using streamer tubes. The best observed response is approximately Gaussian with FWHMpeak = 0.24 with only a small high-charge tail. A well-timed, narrow charge integration gate is essential to remove undesired charge spreading effects from afterpulsing.
