This document describes the beryllium vertex beam pipe that will be used in the CLEO III detector. CLEO is one of the most successful experiments in particle physics. The experiment began in the late 1970's and has been upgraded twice since its installation at Cornell. The CLEO III project is a major upgrade consisting of a new particle identification detector and a new charged tracking system. Concurrent with this upgrade to the detector is an upgrade of Cornell Electron-positron Storage Ring (CESR). This CESR upgrade will include a new set of final focusing magnets that focus the counter rotating beams that collide at the center of CLEO. The CLEO III vertex beam pipe is the interface between the ring and the detector. It is the window between the beam chamber and the sensitive elements of the experiment which are built as close as possible to the collision point of the two beams.
