As the LHC luminosity is ramped up to 3×1034 cm-2 s-1 and beyond, the high rates, multiplicities, and energies of particles seen by the detectors will pose a unique challenge. Only a tiny fraction of the produced collisions can be stored on tape and immense real-time data reduction is needed. An effective trigger system must maintain high trigger efficiencies for the physics we are most interested...
The silicon-vertex-trigger (SVT) [1,2] at CDF is made of two pipelined processors: the associative-memory, AM [3,4], finding low precision tracks (roads) and the track-fitter, TF, refining the track quality with high-precision fits. We propose to extend the SVT use, now mostly focused on B-physics, to high-PT physics as a tracker in the forward/backward region. The upgraded SVT structure is easily...
The CDF Run II level-2 calorimeter trigger is implemented in hardware and is based on a simple algorithm used in Run I. This system has worked well for Run II at low luminosity. However, as the Tevatron instantaneous luminosity increases, the limitation due to the simple algorithm starts to become clear. In this paper, we will present an upgrade path to the level-2 calorimeter trigger system at CDF...
The CDF Run II Level-2 calorimeter trigger is implemented in hardware and is based on an algorithm used in Run I. This system insured good performance at low luminosity obtained during the Tevatron Run II. However, as the Tevatron instantaneous luminosity increases, the limitations of the current system due to the algorithm start to become clear. In this paper, we will present an upgrade of the Level-2...
