Description

During the last two years, our team has developed a cost effective technology of manufacturing various types of micropattern gaseous detectors designed for applications in many fields. The designs of these detectors feature a matrix of thin metallic readout strip located under segmented resistive electrodes. This electrode configuration makes such detectors very robust, allows them to be operated at exceptionally high gas gains, and enables withstanding long-term continuous sparking (if it appears) and achieving a very good 2D position resolution. We will describe the results obtained from systematic studies of these detectors and their optimization for high rate applications. Three examples of successful applications, in which our team is deeply involved, will be presented: CsI-RICH detector prototypes for ALICE upgrade, a prototype of novel double-phase LAr detector with a CsI photocathode immersed inside the LAr and a medical/security applications including to a TOF-PET device. The results so far obtained are very encouraging and show that these new micropattern detectors may have a great future.
