Recent technological advances allow for the construction of instruments
which can survey the sky for clusters of galaxies via the
redshift-independent Sunyaev-Zel'dovich effect, and therefore can test
theoretical models of cluster evolution and constrain the model parameters.
Our work quantifies these expectations by using cluster gas simulations
and the Press-Schechter expression to produce sky maps, and then
simulating the telescope observation of these in detail.
Key constraints on the matter density, the gas evolution in
clusters and the power spectrum can be obtained from the
study of clusters selected from a blank field SZ survey.

described by Jones and Saunders in this volume, has the performance
