“…Originally motivated by the need of reducing the sparking probability in another micro-pattern device, Micromegas [36,37], use of resistive electrodes to locally quench the formation of discharges has been developed also for GEM-like detectors as an alternative to multiple cascaded electrodes [38][39][40] F.

“…The success of resistive GEMs triggered a series of similar developments, which are nowadays are being carried out by several other groups in the framework of the CERN RD51 collaboration [65]. As a result of these efforts it was demonstrated that the resistive electrode approach can be successfully applied to any micropattern gaseous detector and will make them robust and sparkprotected [16,66,67]. The latest designs of resistive micropattern detectors have segmented (on strips) electrodes [68].…”

Nowadays RPCs are in a booming phase: they are successfully used in many experiments, including LHC; there are ambitious plans to use them in several upgrade detectors and in some new experiments as well as in various applications. The aim of this paper is to highlight the main challenges which the RPC community may face in the next few years and which were addressed in talks presented at this conference. Examples could be: new and difficult requirements from experiments (and their upgrades) and applications, optimization and improvements of the existing traditional detector designs, improvement of their characteristics (timing /rate performance, aging, dark current and so on), implementation of new more sensitive electronics, investigation of new materials, development of large-area detectors. We will also review the fast and very promising developments of another type of resistive electrode gaseous detectormicropattern detectors having at least one of their electrodes made of resistive materials. These innovative detectors combine in one design the best features of RPC (spark protection) and micropattern detectors (high granularity-high position resolution).

“…For this reason, in this paper, we focus on this more attractive approach, but to implement it we have modified the designs by manufacturing microdot structures on the top of a thick resistive GEM plate. [18], in which it was suggested to replace the parallel meshes with a resistive micro-hole microstrip detector. In this way, the light (or charge) multiplication region (strips) is geometrically shielded from the CsI photocathode.…”

In the last few years our group have focused on developing various designs of spark-protected micropattern gaseous detectors featuring resistive electrodes instead of the traditional metallic ones: resistive microstrip counters, resistive GEM, resistive MICROMEGAS. These detectors combine in one design the best features of RPCs (sparkprotection) and micropattern detectors (a high position resolution). In this paper we report the progress so far made in developing other types of resistive micropattern detectors: a microdot-microhole detector and a microgap-microstrip detector. The former detector is an optimal electron amplifier for some special designs of dual phase noble liquid TPCs, for example with a CsI photocathode immersed inside the noble liquid. Preliminary tests of such a detector, for the first time built and investigated, are reported in this paper. The latter detector is mainly orientated towards medical imaging applications such as Xray scanners. However, we believe that after a proper gas optimization, these detectors could also achieve a high time resolution and could thus be used in applications as TOF-PET, detection of charged particles with simultaneous high time and position resolution etc.
