DOIAbstract
A telescope made of three OMEGA-ION hybrid silicon pixel detectors has been successfully tested in the heavy ion experiment WA94. Each plane consisted of a single detector with 100G active pixels (500 mum x 75 mum), each one being bump-bonded to the read-out chip, and arranged in 16 columns and 63 rows respectively. With a sensitive area as small as 8000x4725 mum2 several million events with at least one track originating from sulphur-sulphur interactions have been recorded in a few hours. Results on target reconstruction, tracking accuracy and efficiency are presented
