Two micromegas detector quadruplets with an area of 0.5m2 (MMSW) have been recently constructed and tested at CERN and University of Mainz. They serve as prototypes for the planned upgrade project of the ATLAS muon system.
Their design is based on the resistive-strip technology and thus renders the detectors spark tolerant. The applied ḿechanically floatingḿesh design allows for large area Micromegas construction and facilitates detector cleaning before assembly.
Each quadruplet comprises four detection layers with 1024 readout strips and a strip pitch of 415 µm. In two out of the four layers the strips are inclined by ±1.5∘ to allow for the measurement of a second coordinate. We present the detector concept and report on the experience gained during the detector construction.
