Large size multilayer resistive Micromegas detectors will be employed for the Muon Spectrometer upgrade of the ATLAS experiment at CERN. The current innermost stations of the muon endcap system, the 10 m diameter Small Wheel, will be upgraded in the 2019-2020 long shutdown of LHC, to retain the good precision tracking and trigger capabilities in the high background environment expected with...

The resistive Micromegas detectors have already proved to be suitable for precision tracking in dense particle rate environment up to few kHz/cm$^2$. In order to achieve even higher rate capability, with low occupancy up to few MHz/cm$^2$, fine-segmented strips could be replaced by few mm$^2$ pads.
We present here a solution based on small anode pads, overlayed by an insulating layer with a...

Currently m$^2$ large Micromegas detectors with a spatial resolution better than 100 $\mu$m are of big interest for many experiments and applications.
The combination of large size and excellent spatial resolution requires highly sophisticated construction methods in order to fulfil tight mechanical tolerances.
We present a method to survey full sized micromegas detectors on potential...

Recent work demonstrated gas gain in the negative ion gas SF$_6$ using GEMs and Thick GEMs. SF$_6$ is a favorable gas for directional dark matter detection with a TPC because it provides low diffusion (at the thermal limit), strong sensitivity to spin-dependent WIMP dark matter (through the high fluorine content), and full-volume fiducialization (thanks to multiple negative ion species). In...

We have developed a new method for fabricating Micromegas detectors based on thermal bonding technique. A high gain (>10000) and a good energy resolution of 16% (FWHM, 5.9 KeV x-rays) can be obtained for Micromegas detectors built with this method. In order to reduce sparking rate of the detectors, we have also studied resistive anodes by Germanium plating and carbon paste screen printing...
