“…It has a mean of 1.1 and yields a hit multiplicity of 1.7 (defined as the mean excluding the zero-hit bin). After applying cuts, the multiplicity drops to 1.1 which is the nominal value obtained with large-area prototypes [2]. The measured performance are summarised in Fig.…”

Micromegas is an attractive option for a gaseous sampling calorimeter. It delivers proportional and fast signals, achieves high efficiency to minimum ionising particles with a compact design and shows well-uniform performance over meter-square areas. The current R&D focuses on largesize spark-protected Micromegas with integrated front-end electronics. It targets an application at future linear colliders (LC) and possible upgrades of LHC experiments for the running at high luminosity. In the later case, occasional sparking should be suppressed to avoid dead-time and technical solutions using resistive coatings are investigated. Small prototypes of resistive and non-resistive Micromegas were constructed and tested in a beam at DESY. Results are reported with emphasis on the impact of the resistive layer on the detector performance.

“…Micromegas is one detector option for a digital hadron calorimeter at a future linear collider. Large-area prototypes of 1×1 m 2 [1] achieve excellent performance for the targeted application [2]. For higher rate applications, however, occasional sparking creates prohibitive dead-time and should therefore be suppressed.…”

Digital Hadronic Calorimeters (DHCAL) were suggested for future Colliders as part of the particle-flow concept. Though studied mainly with RPC, studies focusing on sampling elements based on Micro-Pattern Gaseous Detector have shown the potential advantages; they can be operated with environment-friendly gases and reach similar detection efficiency at lower average pad multiplicity. We summarize here the experimental test-beam results of a small-size DHCAL prototype, incorporating six Micromegas and two RPWELL sampling elements, interlaced with steel-absorber plates. It was investigated with 2–6 GeV pion beams at the CERN/PS beam facility. The data permitted validating a GEANT4 simulation framework of a DHCAL, and evaluating the expected pion energy resolution of a full-scale RPWELL-based calorimeter. The pion energy resolution derived for the RPWELL concept is competitive to that of glass RPC and Micromegas sampling techniques.

“…A variety of MPGD approaches are being considered for TPC read-out at ILC: GEMs [54], MMs [55] and InGrids [56]. MM [57], GEM [58] and Resistive plate WELL (RPWELL) detectors [59] are considered as potential sensing elements in Digital Hadron Calorimetry at ILC. MPGDs are developed for low-energy nuclear physics experiments.…”

The RD51 Collaboration, in charge of the development and dissemination of MicroPattern Gaseous Detectors (MPGD) since 2008, proposes to extend its activity, after 2018, for a further five-year term. Since the RD51 initial years, the community of MPGD developers and users has grown considerably. It is reflected by the many MPGD-based applications in high energy and nuclear physics experiments as well as in other basic and applied-research fields. They rely on the parallel progress of detector concepts and associated technologies. The cultural, infrastructure and networking support offered by RD51 has been essential in this process. The rich portfolio of MPGD projects, under constant expansion, is accompanied by novel ideas on further developments and applications.The proposed next term of RD51 activities aims at bringing a number of detector concepts to maturity, initiating new projects and continuing the support to the community. Among leading proposed projects are ultrafast, high-rate MPGDs; discharge-free, high-resolution imaging detectors with resistive elements and highgranularity integrated electronics; novel noble-liquid detector concepts, including electroluminescence in gas bubbles; studies of environment-friendly counting gases and long-term sealed-mode operation; optical-readout detectors with radiation-hard imagers for fundamental research experiments, radiography and other domains.The proposed R&D program is also expected to enrich our basic knowledge in detector physics, to form a generation of young detector experts -paving the way to new detector concepts and applications. The vast R&D program requires acquiring additional, up-to-date expertise in advanced technologies.
