Abstract
Two movable tungsten radiation shields were installed on the beam pipe during the upgrade of the CLEO II detector, operating at the Cornell Electron Storage Ring (CESR). This upgrade included the installation o f a silicon vertex detector (SVX) and the purpose of the shields is to protect the SVX readout electronics from synchrotron radiation produc ed during injection and non-high-energy physics operation of CESR. Shi eld motion is controlled remotely by cables, keeping the associated mo tors and controls outside the detection volume. We discuss the design and performance of the radiation shields and the associated control sy stem. (C) 1998 Elsevier Science B.V. All rights reserved.
