Micromegas (MM) are being used as tracking detectors in HEP experiment upgrades. For applications at future accelerator experiments, we are developing the MM technology to increase its rate capability and reach a stable and efficient operation up to particle fluxes of 10 MHz/cm2.
In resistive MM, the anode plane hosts the readout elements overlayed by an insulator and a resistive plane to reduce the spark intensity. We tested several MM prototypes with a high-granularity readout plane, with 1x3 mm2 size pads, and different resistive protection schemas exploiting a pad-patterned layer or two uniform DLC layers.
To cope with the high number of readout channels and allow for the size scalability of the detector avoiding dead areas, we are implementing the integration of the readout electronics in the back of the detector.
We will present measurements to assess the optimal resistive schema and preliminary results on the embedded electronics prototype currently under test
