摘要：

The ALEPH silicon vertex-detector consists out of two layers of silicon detectors. We use detectors of 5 x 5 cm2 with doublesided readout. The signals from the strips are amplified and multiplexed using the CAMEX64 chip. These detectors were operated in a testbeam in September 1989. We measured detector parameters like signal-to-noise ratio, efficiency and resolution. In spring 1990 the inner layer and a part of the outer layer was installed in ALEPH. For the first time doublesided silicon-detectors were used in a physics experiment. Results of the testbeam run and preliminary results of the ALEPH run will be reported including results on track matching and alignment. Plans for future upgrades will be discussed as well.
