Abstract :
The drift chambers making up the Central Tracking region of the DØ detector are being replaced by an 830,000 channel silicon vertex detector and a 90,000 channel scintillating fiber detector. Readout electronics is being designed to be common to both detectors. A custom high-density mixed-technology integrated circuit, mounted in the interaction region, is being used to digitize charge deposited on each silicon strip. Data from the detectors is routed to custom VME Modules via commercially available high speed optical links. Events are stored in up to 12 memory buffers, waiting for intermediate trigger processing and transport to higher level event processing systems. Overall detector read out systems are described. Individual module and system designs are described
