High Level Trigger Software for ATLAS


We are involved in the management of the Atlas Trigger, with leadership in the areas of software coordination and trigger algorithms. We have also represented the interests of several key physics groups in the menu coordination group. RHUL staff and students regularly play their part in operating the trigger, with expert roles and shifts in the Atlas Control Room.

The trigger software project has about ... lines of code, ... developers and we build ... releases per year. Trigger algorithms are produced though collaboration between trigger experts, reconstruction developers and physics analysis groups to give the optimum balance between technical performance (memory, cpu and network usage), the best rejection and least biased selection. This performance has to be validated before use and monitored once it is on-line. Students and staff from RHUL have been involved in all parts of this process, including recent work in electron/photon triggers.
