We have developed large area multi-step avalanche chambers with electr
onic readout for tracking in a very high multiplicity environment in t
he WA98 experiment at the CERN SPS. The operational characteristics of
the detection system is reported. The reconstruction efficiency of th
e chambers varies with the density of charged particles in the range o
f 91-96%. The position resolution has been found to be 0.5 and 1.7mm i
n the horizontal and vertical directions, respectively. (C) 1998 Elsev
