We have developed large area multi-step avalanche chambers with electronic readout for tracking in a very high multiplicity environment in the WA98 experiment at the CERN SPS. The operational characteristics of the detection system is reported. The reconstruction efficiency of the chambers varies with the density of charged particles in the range of 91–96%. The position resolution has been found to be 0.5 and 1.7 mm in the horizontal and vertical directions, respectively.
