Abstract The Phase-I trigger readout electronics upgrade of the ATLAS Liquid Argon calorimeters enhances thephysics reach of the experiment during the upcoming operation atincreasing Large Hadron Collider luminosities.The new system, installed during the second Large Hadron Collider Long Shutdown,increases the trigger readout granularity by up to a factor of tenas well as its precision and range.Consequently, the background rejection at trigger level is improvedthrough enhanced filtering algorithms utilizing the additional informationfor topological discrimination of electromagnetic and hadronic shower shapes.This paper presents the final designs of the new electronic elements,their custom electronic devices, the proceduresused to validate their proper functioning, and the performance achievedduring the commissioning of this system. 

Confronted with tight project deadlines, a development team is often under pressure to make decisions regarding the project (e.g., Which features can be included in the next release? Is the software product ready for release?). In order to make these decisions, it is necessary to obtain information from multiple sources, including source code in different languages and documentation in different formats. In this paper, we present a technique that uses change entries to obtain relevant project information. Our technique, FACTS PT, automatically extracts, traces, aggregates, and visualizes change entries along with other software metrics to provide project information. Results from our case study at the ABC Organization* suggest that the information provided by the FACTS PT is useful to project managers and developers. We also offer lessons learned regarding collecting and presenting information to a team in a proprietary and regulated software development context.
