The MARK III detector is a third generation, general purpose detector designed to operate at the SPEAR e+e - storage ring at SLAC~ Although charged particle multiplicities, which average about four, are not unmanageable at this energy, good detection efficien6y and particle identification are essential for the study of exclusive decay processes. The central detection device for tracking and momentum measurement of charged particles is a large cylindrical drift chamber with a rather novel design, shown in fig. 1. The chamber contains two regions: an inner region with a high density of sense wires, and a * Work supported by the Department of Energy, contract DE-AC03-76SF00515.

N2 - A large cylindrical drift chamber has been constructed for the MARK III detector at SPEAR. The inner layer has a high density of sense wires for the measurement of kinks, vees, and dE dx. The outer layers have a cell design with three sense wires, giving uniform drift behavior and left/right ambiguity resolution within a cell. The chamber has both current division and stereo layers for longitudinal position measurement.
