We present initial results from our AMR Cluster Archive Project - an effort to produce the first large, statistically-complete samples of numerical clusters evolved at high resolution. The first catalog of ~ 100 clusters evolved in a Lambda CDM universe (Omega_o =0.3, Omega_ lambda = 0.7) with purely adabiatic gas physics (best resolution of 15.6h(-1) kpc) is nearing completion. We present preliminary results from this catalog for the evolution of the cluster X-ray luminosity function and temperature function as well the evolution of density profiles and core radii. We also discuss the entropy evolution for this purely adiabatic case. The second catalog of clusters will utilize the same initial conditions but will include non-adiabatic effects such as radiative cooling and galaxy feedback. Simulations for the second catalog are underway. This work was supported by NASA grant NAGW-3152 and NSF grant AST-9896039.
