Abstract
The resistive Micromegas technology can stably operate up to O (10 MHz/cm2) particle rate thanks to novel resistive spark-protection structures suitable for readout pads of a few mm2 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 about 25 cm2 and in the new one with an active area of about 400 cm2. 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
