Abstract

The use of bakelite as electrodes for resistive plate chambers is widespread. The performance of RPC´s, in particular its rate capability, strongly depends on the bulk resistivity of the electrodes. Since the bakelite resistivity changes as a function of temperature and humidity, we have performed several resistivity measurements of a melaminic bakelite sample in order to investigate this dependence. Two sets of measurement at well controlled environmental conditions were performed: the former after relative humidity changes in the range from 80% to 20% at constant temperature, the latter varying the temperature from 15°C to 35°C at constant relative humidity.
