We reportfor thefirsttimeon theperformanceof theSLD Central Drift Chamber (CDC) at SLC, which has been recordingdatasince 1992. The low mass of the chamber and the use-of a gas characterized by both a low drift velocity and low diffusion constant help to minimize the drift-distance measurement errors. We describe some of the calibrations and corrections applied to the dam, and report on the res...

The MPS II detectors are narrow drift space chambers designed for high position resolution in a magnetic field and in a very high particle flux environment. Central to this implementation was the development of 3 multi-channel custom IC's and one multi-channel hybrid. The system is deadtimeless and requires no corrections on an anode-to-anode basis. Operational experience and relevance to ISABE...
