The design and operation of the CLEO III silicon vertex detector is described in this report. This detector consists of four layers of double-sided silicon wafers covering 93% of the solid angle. ...After initially meeting its signal-to-noise and spatial resolution design goals, the
r−
φ side efficiency of layers 1 and 2 decreased dramatically due to radiation-induced sensor effects.

The CLEO-III silicon vertex detector is a 4-layer device with double-sided silicon sensors arranged in a barrel design, covering 93% of the solid angle. After initially meeting its design goals of ...signal-to-noise performance and spatial resolution, the signal efficiency deteriorated on the rφ sensor side in the two innermost layers due to radiation induced sensor effects. Operation of the two outermost layers and the
z-coordinate readout in all layers is stable.

CLEO III is the new experimental phase of the CLEO experiment at the CESR accelerator. Both the accelerator and the detector have recently been upgraded. A new charged particle tracking system with ...the addition of a ring imaging Cherenkov particle identification system has been installed. A major part of the tracking system upgrade was the construction of a new four-layer double-sided silicon tracker with 93% solid angle coverage and new readout electronics. The CLEO III upgrade was completed in February 2000 with the installation of the silicon detector. CLEO III has finished the commissioning phase and is now taking data. The design of the detector and first performance results are presented here.
