Speaker
Description
The CMS experiment at the CERN Large Hadron Collider (LHC) operates a sophisticated trigger and data acquisition (DAQ) system, designed to efficiently select and record collision events of interest from an input rate of up to 40 MHz. The L1 trigger, implemented with custom hardware, uses coarse detector information to reduce the event rate to $\mathcal{O}(100)$ kHz. The HLT, software-based and running on a large computing farm, further refines the event selection using full detector granularity, bringing the rate down to around 5 kHz for permanent storage of full event information. The collection, processing, and storage of the data is handled by the high-throughput DAQ system, which enables event building at a rate of $\mathcal{O}(100)$ kHz, leveraging state-of-the-art network technologies. An overview of the architecture, performance, and developments of the trigger and DAQ systems is presented.
