In a particle physics experiment, the trigger is a fast online ("live") selection system that decides which events are interesting enough to be recorded for further offline analysis and which events are to be discarded. In the ATLAS experiment at the Large Hadron Collider (LHC), the trigger is currently implemented as a piece of software that examines the results of each collision that occurs, for instance, between protons. While the envisioned high-luminosity upgrade of the LHC is expected to enable us to better understand the electroweak symmetry breaking mechanism -responsible for giving mass to particles through the Higgs boson- and surrounding potential new physics, it is also foreseen that, because of the greatly increased number of collisions per second, the trigger will be a major challenge. Real-time tracking of charged particles (i.e., reconstruction of their trajectories to identify their nature and measure their momenta) would solve many problems while maintaining a highly efficient trigger. The Fast TracKer system (FTK) is a hardware-based tracking system designed to overcome the issues arising from the increased luminosity, and which we will integrate into the LHC-ATLAS experiment operation from 2015. The required short latency in the system will be achieved mainly by a massive parallelism in the system. The so-called associative memory approach and high-speed serial communication are the key technologies to achieve such massive parallelism. In this seminar, I will introduce the application of this cutting-edge technology to the high-energy frontier hadron collider experiment, and show the current situation and the future prospect of the projects.
