The Decay Detector is a compact array of 10 mum pitch silicon microstrip detectors designed to give charged track data which is sufficient, both in quantity and in precision, to allow reconstruction of beauty particle decays. It has been built for Beatrice, a fixed-target hadroproduction experiment at CERN. This ''electronic bubble chamber'' consists of sixteen 5 mm x 5 mm microstrip planes comprising more than 8000 detector channels packed into a volume of less than 0.8 cm3. The pulse heights of all channels are read by analogue front-end electronics and are then compared with individually set thresholds and pedestals. The performance of the Decay Detector has been studied in a test beam and data are presented on its spatial precision, efficiency, and other characteristics.

Abstract
The Decay Detector is a compact array of 10 mum pitch silicon microstrip detectors designed to give charged track data which is sufficient, both in quantity and in precision, to allow reconstruction of beauty particle decays.

This ''electronic bubble chamber'' consists of sixteen 5 mm x 5 mm microstrip planes comprising more than 8000 detector channels packed into a volume of less than 0.8 cm3. The pulse heights of all channels are read by analogue front-end electronics and are then compared with individually set thresholds and pedestals.
