Abstract

The CLEO collaboration has embarked on an ambitious upgrade of the CLEO detector to match the upgrade of the CESR accelerator to luminosities of 2 x 10(33) cm(-2)sec(1). This will bring a factor ten improvement in the measurement of rare B decays and hence, increased sensitivityto physics at high mass scales and also the possibility of measuring CP violation. The upgrade includes a new four layer double-sided silicon detector. Each double-sided silicon wafer is 2.6 cm x 5.1 cm x 300 mu m. To maximize solid angle coverage with minimal material in the detector volume the detector chains are very long, up to 5 detectors perelectronic readout channel, resulting in large series resistance and large detector capacitance. Moderate backgrounds permit the electronics to operate with a 1-3 mu s shaping time. A new front-end low noise preamplifier is being developed to maximize the signal-to noise ratio, along with a modified SVX chip used for analog to digital conversion and sparsification. The detectors are connected to the electronics hybrid by a thin double sided kapton flex circuit. The length of the detector chains also requires novel mechanical support structures - CVD diamond beams are the baseline solution. We are currently near the end ofthe prototype stage for all aspects for the project and will move into production by late summer. The detector will be installed in early 1998.
