文摘
We describe the most recent efforts made by various groups in implementing resistive electrodes in micropattern gaseous detectors with the aim to combine in the same design the best features of Resistive Plate Chambers (RPCs)¡ªfor example, their robustness and spark-protection property¡ªwith the high granularity and thus the good position resolution offered by microelectronic technology. In the stream of this activity, we have recently developed two novel detectors with resistive electrodes; one based on resistive micromeshes and the second one is a microstrip gas chamber with resistive electrodes. We have demonstrated that the resistive meshes are a convenient construction element for various designs of spark-protective detectors, for example of parallel-plate or micropattern types. These new detectors enable considerable enhancement of the RPC and micropattern detectors applications since they feature not only high position resolution but also relatively good energy resolution (25-30 % full width at half maximum and at 6 keV) and, if necessary, they can operate in the cascaded mode, allowing the achievement of a high overall gas gain.
