Resumo
Detectors with highly resistive electrodes, particularly
RPCs, have been studied extensively in recent years. Several
authors considered the effect of rate on the detector response
(efficiency) and a few also associated with the rate, in a rather
qualitative manner, the charge per event, i.e., the current.
Here, without loss of generality of the results obtained, rate
effects are studied with a classical cylindrical counter
geometry and different gas mixtures. To a high accuracy, the
observed behavior, both for the proportional mode and for the
transition to streamers, is quantitatively and accurately
interpreted as loss of voltage on the dielectric due to the
current generated in the detector, with direct consequences
for the local electric field in the avalanche region. Results
obtained in the self quenching streamer (SQS) mode fail the
previous interpretation and clearly need further research.
