Spatial-Resolution Of Plastic Streamer Tubes With Wide Strip Readout

We have studied the achievable spatial resolution of a plastic streamer tube with pickup strips perpendicular to the anode wire. Making use of the fact that low cathode resistivity and/or large integration time broaden the induced charge distribution, we have obtained a spatial resolution better than 400-mu-m for approximately 3 cm wide strips. This value is comparable with the best results (approximately 350-450-mu-m) obtained with the usual approximately 1 cm wide strips.
