Description

The future of HEP experiments foresee new upgrades of the current accelerators (HL-LHC) and the design of high energy and very high intensity new particle accelerators (FCC-ee/hh, EIC, Muon Collider). This opens new challenges to develop cost effective, high efficiency particle detectors operating in high background and high radiation environment.

An R&D project is ongoing in order to consolidate the MPGD technology for particle fluxes up to 10 MHz / cm$^2$ with a high-granularity low occupancy readout on pads with a dimension of the order of few mm$^2$. The radiation hardness and the feasibility to build large scale detectors for future high energy physics experiments are also part of the main objectives of the project.

Various prototypes of small-pad resistive Micromegas with different configuration and construction techniques have been built, tested and characterized. In particular the resistive schemes explored are either based on embedded resistors or using uniform Diamond-Like Carbon (DLC) resistive foils. The most recent results in terms of rate capabilities, gain, energy, space and time resolutions will be presented.
