VMM3 Readout Chips Calibration and Performance Response to Pressure in Micromegas Detectors — •Ksenia Solovieva1, Thorwald Klapdor-Kleingrothaus2, Patrick Scholer2, Vladislavs Plesanovs2, and Ulrich Landgraf2 — 1Imperial College London, London, UK — 2Albert-Ludwigs University, Freiburg, Germany
During the ongoing LHC Long Shutdown, the ATLAS detector upgrade includes the implementation of the New Small Wheels as part of the Muon Spectrometer. One of its detector technologies is the MicroMesh Gaseous Detector (MicroMegas) used for improved tracking and triggering in a higher particle rate environment.
For the purpose of investigating the MicroMegas detector readout, prototype detectors were set up and read out with dedicated Front End Boards containing VMM3 ASICs. Two logic chains for triggering were successfully implemented, one for cosmic muons and one including the ion signal of the micromesh in the detector. This presentation discusses the developed procedures and presents the results of calibration and gain studies.
