The Silicon Vertex Trigger (SVT) in the CDF experiment at Fermilab performs fast and precise track finding and fitting at the secondtrigger level and has been a crucial element in data acquisition for Run II physics. However, as luminosity rises, multiple interactionsincrease the complexity of events and thus the SVT processing time, reducing the amount of data CDF can record. The SVT upgradeaims to increase the SVT processing power to restore the original CDF DAQ capability at high luminosity. We describe the SVTupgrade, consisting of a new Associative Memory 16 times larger than the existing one, and new faster Track Fitter and Hit Bufferboards to take advantage of these patterns. We describe the existing system, the upgrade, tests and performance.

Abstract
The Silicon Vertex Trigger (SVT) in the CDF experiment at Fermilab performs fast and precise track finding and fitting at the secondtrigger level and has been a crucial element in data acquisition for Run II physics. However, as luminosity rises, multiple interactionsincrease the complexity of events and thus the SVT processing time, reducing the amount of data CDF can record. The SVT upgradeaims to increase the SVT processing power to restore the original CDF DAQ capability at high luminosity. We describe the SVTupgrade, consisting of a new Associative Memory 16 times larger than the existing one, and new faster Track Fitter and Hit Bufferboards to take advantage of these patterns. We describe the existing system, the upgrade, tests and performance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
