The Resistive Plate Chamber (RPC) detectors are widely used thanks to their excellent time resolution and low production cost. At the CERN LHC experiments, the large RPC systems are operated in avalanche mode thanks to a Freon based gas mixture containing C2H2F4, SF6 and iC4H10. Unfortunately C2H2F4 and SF6 are considered greenhouse gases with high impact on the environment. Furthermore the...

Our group is developing gaseous pixel detectors by using micromegas-based amplification structures on top of CMOS pixel readout chips of the Medipix family. By means of wafer post-processing techniques we add a spark-protection layer and a grid to create the amplification region above the chip. An inserted gas layer and cathode plane above the grid create a complete gaseous detector able to...

GridPix detectors combine the advantages of a high granularity readout based on a pixel ASIC with a Micromegas gas amplification stage. By producing the Micromegas with photolithographic postprocessing techniques directly on the ASIC a very good alignment of grid holes with readout pixels can be reached. Thus, the charge avalanche started by a single primary electron can be collected and...

Future experiments in Particle and Astro-particle Physics pose a growing demand for cost-effective large-area imaging detectors, capable of operating stably over a broad range of conditions. Promising candidates are detectors based on the Thick Gas Electron Multiplier (THGEM) principle. Among them are: the cascaded-THGEM, WELL, Resistive-WELL (RWELL) and the recently introduced Resistive-Plate...
