[en] A silicon microstrip vertex detector is under construction for the Collider Detector at Fermilab (CDF). The vertex detector, which contains close to 40000 individual strips, will be read out with a full custom VLSI circuit, the SVX chip, developed for this application. This paper describes the integration of this circuit into a full front end readout system. Problems of noise, packaging, signal and power distribution, control and readout, testing, and quality control are discussed. Results are presented on the operation of a prototype system including silicon strips

[en] We describe the design and construction of a large drift chamber of a novel design well adapted for operation in high magnetic fields and in the high track density environment of hadron colliders. (orig.)

[en] An SVX sector prototype was operated at Fermilab in a configuration very close to the version to be installed in CDF. The sparse readout features of the SVXD chip, which provide the local data compaction that is necessary to deal with the detector high number of channels (40 K) and typical Tevatron luminosities, were tested for the first time with a 230 GeV/c pion beam. A good background rejection and high hit efficiency was demonstrated in this mode of operation, with adequate signal to noise ratio and spatial resolution. (orig.)

[en] The Intermediate Silicon Layers (ISL) detector is presently being built as part of CDF upgrades. The ISL is a large radius (28 cm) silicon tracker with a total active area of about 3.5 m². The challenge is to build a device which provides precise 3D points introducing a minimal amount of material for the supporting structure. The design and the status of the project are described

[en] The Intermediate Silicon Layers Detector is presently being built as part of the CDF upgrades to prepare for the next Tevatron data taking run, scheduled to start in the year 2000. The ISL will be located in the radial region between the Silicon Vertex Detector and the Central Outer Tracker. It will add tracking in the forward region and significantly improve tracking in the central region. Together with the SVX II, the ISL forms a standalone, 3D silicon tracker. In this article we present the design of the ISL and the current status of its construction. (author)

[en] Fermilab plans to deliver 5-15 fb^-1 of integrated luminosity to the CDF and D0 experiments. The current inner silicon detectors at CDF (SVXIIa and L00) will not tolerate the radiation dose associated with high-luminosity running and will need to be replaced. A new readout chip (SVX4) has been designed in radiation-hard 0.25 μm, CMOS technology. Single-sided sensors are arranged in a compact structure, called a stave, with integrated readout and cooling systems. This paper describes the general design of the Run IIb system, testing results of prototype electrical components (staves), and prototype silicon sensor performance before and after irradiation

[en] The Intermediate Silicon Layers (ISL) detector is currently being built as part of the CDF II detector upgrade project. The ISL detector will significantly improve tracking in the central region and, together with the Silicon Vertex detector, provide stand-alone 3D track information in the forward/backward regions. In this article, we present the quality of the production sensors manufactured by Hamamatsu Photonics, which account for roughly half of the silicon sensors used in the ISL detector

[en] 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. (orig.)

[en] Technical details and methods used in constructing the CDF silicon vertex detector are presented. This description includes a discussion of the foam-carbon fiber composite structure used to silicon microstrip detectors and the procedure for achievement of 5 μm detector alignment. The construction of the beryllium barrel structure, which houses the detector assemblies, is also described. In addition, the 10 μm placement accuracy of the detectors in the barrel structure is discussed and the detector cooling and mounting systems are described. 12 refs

[en] 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. (orig.)
