THE METHOD OF POSITION SENSING BY CHARGE DIVISION IN GAS SAMPLING SHOWER COUNTER

Practical formulas for calculating position sensing by charge division were given.They were applied to experiments on self-quenching streamer (SQS) tubes with different shorter wire lengths (smallest resistance 425Ω) and the position resolution obtained was 1.1% for a 37.3cm wire.The error of position sensing by charge division on single tube was compared to that on parallelly connected double tuble tubes.Possible errors of determing position of the shower "Axis" by charge division method on the wires were studied.
