Book Description
The 8 layer, 720k channel CDF Run II silicon detector is an essential part of the heavy flavor tagging and forward tracking capabilities of the CDF experiment. A summary of the experience in commissioning and operating this double-sided detector during the first 2 years of Run II is presented. The performances of the silicon in term of resolution, efficiency are also described. The results of the studies of radiation damage and the expected operational limits are discussed. A short description of the SVT, the Level 2 Silicon Vertex Trigger, one of the major upgrades related to the new silicon device is also presented. Finally, some of the many physics results achieved by means of the new Silicon+SVT machinery are also reviewed.

Book Description
The CDF silicon vertex detector is being upgraded for use in Run II of the Fermilab collider. The increased luminosity in Run II, coupled with the desire for increased acceptance and secondary vertex triggering, necessitates a complete redesign of the previous generation tracker. Details of the design are described.

Book Description
A microstrip silicon detector SVX II has been proposed for the upgrade of the vertex detector of the CDF experiment to be installed for run II of the Tevatron in 1998. Three barrels of four layers of double sided detectors will cover the interaction region. The requirement of the silicon tracker and the specification of the sensors are discussed together with the proposed R & D to verify the performance of the prototypes detectors produced by Sintef, Micron and Hamamatsu.

Book Description
A substantial portion of the Run IIa silicon detectors of the CDF experiment will not perform adequately for the duration of Run IIb (15 fb−1) because of radiation damage. The Silicon Vertex Detector (SVX-II) and Layer 00 will be fully replaced at the end of Run IIa. The Run IIb silicon tracker has a baseline design that safely achieves the required radiation tolerance by using single sided sensors that are actively cooled. The new Run IIb castellated layout contains more silicon surface area and has a more uniform radial distribution. It minimizes the number of hybrid and sensor varieties providing quick construction and assembly. The total mass in the tracking volume is reduced by eliminating unnecessary the passive material from the CDF volume.

Book Description
In 2001, an upgraded silicon detector system was installed in the CDF II experiment on the Tevatron at Fermilab. The complete system consists of three silicon micro-strip detectors: SVX II with five layers for precision tracking, Layer 00 with one beampipe-mounted layer for vertexing, and two Intermediate Silicon Layers located between SVX II and the main CDF II tracking chamber. Currently all detectors in the system are operating at or near design levels. The performance of the combined silicon system is excellent in the context of CDF tracking algorithms, and the first useful physics results from the innermost Layer 00 detector have been recently documented. Operational and monitoring efforts have also been strengthened to maintain silicon efficiency through the end of Run 2 at the Tevatron.
