First results from the 1994 lead beam run of WA97

WA97 is designed to study strange and multi-strange baryon and anti-baryon production in 160 A GeV c PbPb collisions at the SPS with a telescope of silicon microdetectors. Four planes of silicon pixel detectors were successfully employed during the 1994 Pb run. A total of 60M central PbPb events were collected. We describe the experimental setup and report on some preliminary results from the off-line analysis.
