Measurement of temperature of ICM with ASCA are ideal for studying 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. Co-Is: 1 M. PIERRE SACLAY FRANCE (No Co-I contact data) 2 J. HUGHES CFA USA 3 R.
