Abstract

The results of the research and development on the silicon detectors for the CLEO III vertex detector are reported. Since the CLEO III detector design requires up to five detectors to be daisy chained, capacitance must be minimized. We have developed a 5 cm×2.6 cm double metal (z-side) detector with less than 10 pF strip capacitance on each side. In addition, we have developed a novel p-barrier design (to isolate strips on the ohmic side) which nearly eliminates the Johnson noise component arising from the ohmic character of this type of isolation. We also report noise and cosmic ray signal data from various length ladders
