Trigger and Software@UCL

UCL has been a big contributor to the development/maintenance/optimization of software for the ATLAS High Level Triggers (HLT) as well as offline software. In terms of offline software, we are in charge of the Atlantis Event Display and the online Event Displays framework running in the ATLAS Control Room. We have also fully developed and maintain the RunTimeTest, the framework used extensively in ATLAS for testing automatically all software packages in various releases and configurations of the ATLAS software project. In HLT, we were the lead developers of the fast pattern recognition algorithms for the Level-2 Trigger of ATLAS during Run-1, and continue a key involvememnt in the operations, validation and monitoring of the HLT tracking. we have also been leading the Jet Trigger and b-jet Trigger signature groups and have key roles in the Trigger Menu activities and the Monte Carlo production for the Trigger optimization studies.
