Investigation of a multiplexed readout for Micromegas detectors — •Christoph Jagfeld, Otmar Biebel, Bernhard Flierl, Maximilian Herrmann, Ralf Hertenberger, Felix Klitzner, Philipp Lösel, Ralph Müller, Maximilian Rinnagel, and Chrysostomos Valderanis — LMU, Munich

In Micromegas detectors (Micro-MEsh GAseous Structures), a modern form of micro-pattern gaseous detectors, every single micro strip is read out by a single electronic channel. For large scale Micromegas detectors this results in a huge number of electronic readout channels and corresponding electronics, leading to high power consumption and heat dissipation. To reduce the number of electronic readout channels by a factor of two a multiplexed readout scheme has been developed and investigated.
Tests at the tandem accelerator in Munich with 20MeV protons at an angle of incidence of 20^∘ have been performed to observe the impacts of the multiplexed readout on the angular resolution and signal pulse height.
To observe the impacts on the efficiency and spacial resolution studies with cosmic muons have been done.
These tests, which will be presented show the usability of the multiplexed readout for the Micromegas detector.
