Double-sided readout silicon strip detectors for the aleph minivertex

Abstract Large double-sided readout silicon strip detectors have been fabricated for the Aleph minivertex. We have tested them with a β-source and have observed charge collection and capacitive charge division both on the junction side and on the ohmic side. A charge correlation has been observed between the two faces and can be used to reduce ambiguities in the case of two particles crossing the same wafer.
