Title: Application of highly resistive material for particle detection
Host: Chertok
Room: 416
Highly resistive materials (resistivity about 10^10 ohm cm) are used to make resistive electrodes of some detectors in particle physics. These detectors can be tuned to achieve a timing resolution of about 1 nanosecond, good enough to trigger high energy muons. With narrow gas gaps, the timing resolution is improved by a factor of 100, good enough to identify particles by time of flight. With finer division of the electrode, the spatial resolution of these detectors is improved by one order of magnitude over wire chambers, good for tracking in high rates.
The development of these detectors, Resistive Plate Chamber (RPC), multi-gap RPC and Resistive Micropattern Detectors, in particle physics will be presented in this talk.
