   Clusters of galaxies are key objects for understanding the origin and
   growth of structure in the universe. Measurement of temperature of
   ICM with ASCA are ideal for studying the potential wells, and thus
   the dynamical state, of these massive systems. We have selected 8
   objects from the ROSAT All Sky Survey and undertaken to obtain a
   complete set of high resolution follow-up observations including
   studies of X-ray morphology, optical spectroscopy/photometry, and
   radio and IR measurements of cluster galaxies, which provides deep
   insights into the structures and coherent picture of young cluster
   environments. All observations except for ASCA have already finished.
   The porject will be complete by the observations of ASCA.
