Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS                      
  Title: X-RAY TEMPERATURES FOR A COMPLETE SAMPLE OF DISTANT CLUSTERS                    


Abstract:
 We propose to begin the systematic study of the spctra of high redshift clusters of
 galaxies. Specifically, we will make the first determinations of the cluster
 temperature function at a redshift other than zero. This measurement will
 discriminate among various models of the evolution of the X-ray gas in clusters and
 will also determine the mass density fluctuation spectrum on cluster scales. This
 proposal requests observations of the last four clusters in our complete sample.
