THE SILICON VERTEX DETECTOR OF THE COLLIDER DETECTOR AT FERMILAB

Abstract A silicon microstrip vertex detector has been constructed and installed in the Collider Detector at Fermilab. The device has been designed to operate at a hadron collider. It began collecting data in May of 1992 and has functioned within specification. Technical details are presented on all aspects of the system and its performance.

THE CDF SILICON VERTEX DETECTOR

A silicon strip vertex detector was designed, constructed and commissioned at the CDF experiment at the Tevatron collider at Fermilab. The mechanical design of the detector, its cooling and monitoring are presented. The front end electronics employing a custom VLSI chip, the readout electronics and various components of the SVX system are described. The system performance and the experience with the operation of the detector in the radiation environment are discussed. The device has been taking colliding beams data since May of 1992, performing at its best design specifications and enhancing the physics program of CDF.

PROGRESS IN THE CONSTRUCTION OF THE CDF SILICON VERTEX DETECTOR

Abstract The mechanical design and construction progress of the CDF silicon vertex detector is described. Results on the location accuracy of the silicon strip detectors are presented and indicate an initial placement uncertainty of less than 10 μm. The water and gas cooling system, which is constructed of low mass materials and is used to remove heat from the readout electronics, is briefly described. Measurements of the performance of the silicon strip detectors are also given and show > 98.5% functioning strips for the assembled SVX detector.

Operation of the CDF silicon vertex detector with colliding beams at Fermilab

In this paper we briefly describe the main features of the CDF Silicon Vertex Detector (SVX) and discuss its performance during actual colliding beam operation at the Fermilab Tevatron. Details on S/N ratio, alignment, resolution, and efficiency are given.
