Abstract
The ATLAS Muon Drift Tube (MDT) ReadOut Drivers (MROD), 204 VME modules that are an essential part of the readout chain of the 1,150 MDT chambers, have been in operation for more than 15 years and are expected to remain in operation until about 2026. In the event of extensive failures the number of spare MROD modules may be insufficient. However, deployment of an adapted version of the Front-End LInk eXchange (FELIX) system, a new component of the ATLAS data acquisition (DAQ) infrastructure, may overcome potential MROD failures. This paper describes the design, functionality and performance of this adapted version, referred to as FELIX-MROD, and the test results of its integration into the ATLAS DAQ system.
