Abstract
In view of the ATLAS Phase II Upgrade, a proposal to extend the detector acceptance of the muon system up to |η| ∼ 4 is being considered. The extension of the muon detection, together with the extension of the inner detector to the same range in η, has been demonstrated to enhance physics performance. The new high-η muon tagger should cope with extremely high particle rate, dominated by background hits up to about 10 MHz/cm2 in the most forward region. We present the development of resistive micromegas with O(mm2) pad readout aiming at precision tracking in high rate environment without efficiency loss up to several MHz/cm2. A first prototype has been designed, constructed and tested. It consists of a matrix of 48 × 16 pads. Each pad has rectangular shape with a pitch of 1 and 3 mm in the two coordinates.
