FELIX-MROD, a FELIX-based data acquisition system for the ATLAS Muon Drift Tubes

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.

The LCFIVertex package: vertexing, flavour tagging and vertex charge reconstruction with an ILC vertex detector

The precision measurements envisaged at the International Linear Collider (ILC) depend on excellent instrumentation and reconstruction software. The correct identification of heavy flavour jets, placing unprecedented requirements on the quality of the vertex detector, will be central for the ILC programme. This paper describes the LCFIVertex software, which provides tools for vertex finding and for identification of the flavour and charge of the leading hadron in heavy flavour jets. These tools are essential for the ongoing optimisation of the vertex detector design for linear colliders such as the ILC. The paper describes the algorithms implemented in the LCFIVertex package, as well as the scope of the code and its performance for a typical vertex detector design.
