Development of a ReadOutDriver (ROD) for ATLAS micromegas

Abstract

Microstructured gaseous detectors are a possible replacement technology for the inner part of the forward muon spectrometer of the ATLAS detector, when the luminosity of the LHC will increase beyond the design value. During the shutdown 2011/2012, several small micromegas detectors have been installed in ATLAS between the inner tracker and the calorimeter as well as on the small wheel section. To read out these detectors along with the other ATLAS systems, a readout driver has to be developed, that integrates this subsystem into the ATLAS data acquisition infrastructure, including the trigger handling, slow control, event building and data formatting.
