Development of innovative micro-pattern gaseous detectors with resistive electrodes and first results of their applications

• The paper summarizes our latest progress in the development of newly introduced micro-pattern gaseous detectors with resistive electrodes. These resistive electrodes protect the detector and the front-end electronics in case of occasional discharges and thus make the detectors very robust and reliable in operation. As an example, we describe in greater detail a recently developed GEM-like detector, fully spark-protected with electrodes made of resistive kapton. We discovered that all resistive layers used in these studies (including kapton) that are coated with photosensitive layers, such as CsI, can be used as efficient photocathodes for detectors operating in a pulse counting mode. There is a description of the first applications of such detectors combined with CsI or SbCs photocathodes for the detection of UV photons at room and cryogenic temperatures.
