An overview of the system architecture and algorithms used for the DØ Central Track Trigger (CTT) in the Run 2 of the Fermilab Tevatron Proton-Antiproton Collider is presented. This system uses information from the newly commissioned Central Fiber Tracker and Preshower Detectors to generate Level 1 trigger decisions. It also generates lists of seed tracks(More)
This article describes the development of a direct-current (dc) superconducting transformer system for the high current test of superconducting cables. The transformer consists of a core-free 10,464 turn primary solenoid which is enclosed by a 6.5 turn secondary. The transformer is designed to deliver a 50 kA dc secondary current at a dc primary current of(More)
The DØ experiment was upgraded in spring 2006 to harvest the full physics potential of the Tevatron accelerator at Fermi National Accelerator Laboratory, Batavia, Illinois, USA. It is expected that the peak luminosity delivered by the accelerator will increase to over 300× 10 cms. One of the upgraded systems is the Central Track Trigger (CTT). The CTT uses(More)
An overview of the DØ Central Track Trigger (CTT) for the Tevatron Run 2 program is presented. This newly commissioned system uses information from the DØ Central Fiber Tracker and Preshower Detectors to generate trigger information for the first level of the three-tiered DØ Trigger. The system delivers tracking detector trigger decisions every 132 ns,(More)
