Abstract
The design and the performance of a prototype detector based on MicroMegas technology with two detection layers in a common gas volume, suited for applications in small spatial volumes in high rate environments at, for example at the ATLAS detector, is discussed in this proceeding. Each detection layer has an active area of 9 x 9 cm2 with a two-dimensional strip readout and is separated by a common gas region with a height of 14 mm. A micro-mesh, working as a cathode, is placed in the middle of the common gas volume separating it into two individual cells. This setup allows for a precise angle reconstruction of incoming particles with a precision of up to 1.9◦ using a detector with reduced material budget, compared to current detector designs. In addition, we present first results of performance studies on the prototype detectors based on cosmic muon measurements at the cosmic ray measurement facility at the University of Mainz. It should be noted that this design reduces multiple scattering with makes the detector also suitable for the measurement of low energy beam experiments.
