Abstract

The Collider Detector at Fermilab (CDF) incorporates a Silicon Vertex Detector (SVX) in the study of proton antiproton collisions at the Fermilab Tevatron Collider. We describe here our experience with SVX radiation protection issues during the commissioning and subsequent operation of the Collider. We outline the catalog of typical accelerator loss mechanisms, the radiation dose associated with each, and our eventual protection strategy in each case. We map the total radiation dose received by the SVX in space as well as in time. We also discuss measured radiation damage to the SVX, and its correlation with the independently measured radiation dose
