摘要：

The OPAL experiment at the CERN LEP collider recently upgraded its silicon strip microvertex detector from one coordinate readout (phi only) to two coordinate readout (phi and z). This will allow for three dimensional vertexing and should improve lifetime measurements as well as b-jet tagging and identification. This paper describes the new microvertex detector system with emphasis on the novel techniques and new components used to obtain the second coordinate information. Some preliminary results on detector performance from data taken in the current LEP run are presented.
