The Silicon Vertex Trigger upgrade at CDF

Developement of 3D Vertically Integrated Pattern Recognition Associative Memory (VIPRAM)

“…The SVT approach was highly successful, and CDF was the first hadron collider experiment in HEP to incorporate a fast secondary vertex track trigger [3] [4]. It finds all tracks emanating from each collision and precisely measures their properties within about 30 microseconds after the collision.…”

Measurement of WW + WZ production cross section and study of the dijet mass spectrum in the ℓν + jets final state at CDF

“…CDF employs an innovative processor SVT [30] for the online track reconstruction in the silicon detector. The SVT was upgraded [31] to cope with the higher Tevatron luminosity. The SVT reconstruction is precise enough for online identification of secondary vertexes of B hadron decays (displaced by the primary interaction point).…”

Measurement of electroweak single top quark production in proton-antiproton collisions at 1.96 TeV

“…Silicon information is processed by the Silicon Vertex Tracker (SVT) [49], a system that rapidly analyzes the silicon data to look for a displaced vertex. The calculations of the different systems (calorimeter, COT, and silicon) are sent to a single computer that analyzes the data and decides whether to accept the event.…”
