Investigation of square meter sized Micromegas Quadruplets with Cosmic Muons — •Maximilian Herrmann, Otmar Biebel, Bernhard Flierl, Ralf Hertenberger, Felix Klitzner, Philipp Lösel, Ralph Müller, and Chrysostomos Valderanis — LMU München
Square meter sized Micromegas quadruplets will be used in collision experiments for muon tracking.
The Cosmic Ray Test Facility (CRF) in Garching is well suited for the investigation of these detectors with cosmic muons.
The CRF consists of two Monitored Drift Tube Chambers (MDTs) for precise tracking in one dimension.
A trigger and a coarse segmentation in the direction along the tubes is achieved via a scintillator hodoscope.
A quadruplet with an active area of about 2 m2 fits well in the 9 m2 active area of the CRF and can be investigated with tracks inclined between ± 30 degrees to the zenith angle.
We present results for the performance of Micromegas quadruplets based on measurements done in the CRF.
Geometrical properties of the segmented readout anodes are reconstructed from the deviations to track predictions of the MDTs.
The position resolution is investigated to estimate the track prediction accuracy.
Homogeneity in pulse height and efficiency will be discussed.
