In recent years, Micromegas detectors became more and more important for large scale tracking systems in particles physics. The first Micromegas quadruplet that has been built at CERN features an active area of 0.4 m^2 per plane and is based on the resistive-strip technology, which can be used for precision tracking in high rate background environments. The detector was built in a modular way. The quadruplet consists of two double-sided readout panels and three support (or drift) panels equipped with the micromesh and the drift electrode. The panels are bolted together such that the detector can be opened and cleaned, if required. Here, we present the results of the
panel alignment as measured after assembly of the detector and performance studies in a high-rate radiation environment at the GIF++ facility.
