Small-pads resistive micromegas

Resistive micromegas is now a mature technology for High Energy Physics experiments. In the ATLAS experiment at CERN 128 multilayers large size $(~2 m^2)$) micromegas chambers will be employed in the upgrade of the Muon Spectrometer (2019/2020), and will operate at moderate hit rate up to about $15 kHz/cm^2$ during the phase of High-Luminosity-LHC . Future upgrades and detectors at future accelerators will require operation at rates up to three orders of magnitude higher. In this paper we present the development of micromegas with a small-pads readout (few $mm^2$ in size) aiming at precision tracking in high rate environment without efficiency loss up to a few $MHz/cm^2$. The detector layout and the construction technique will be reviewed, along with the first results obtained with radioactive sources. Outlooks on future developments will also be illustrated.
