Description
The resistive Micromegas technology can stably operate up to O(10 MHz/cm$^{2}$) particle rate thanks to novel resistive spark-protection structures suitable for readout pads of a few mm$^{2}$ area. These structures are made by Diamond-Like-Carbon (DLC) in a double-layer configuration in most of the investigated detectors with active surfaces of $\sim 25\, \text{cm}^{2}$ and in the new one with an active area of $\sim 400 \,\text{cm}^{2}$. Specifically, the DLC foils have a surface resistivity of $\sim 30 \, \text{M}\Omega/\square$ in the last prototype. The results of the performance in terms of gain, rate capability, robustness, dependence on the irradiated area, and space-time dedicated studies will be presented. With the proven high performance of the medium size detector and the already-started construction of a high granularity resistive Micromegas with an even larger area, our R&D is reaching the goal of establishing the technology for future large-scale and high-rate employment in Particle Physics and other fields.
