One of the main goals of the present heavy-ion reaction studies at the AGS and CERN is the understanding of the space-time evolution of the particle and energy density produced in such collisions. These are necessary ingredients if one wants to understand quantitatively the properties of matter at high temperature and density. In that respect, the study of inclusive global variables such as the transverse energy distribution gives valuable information on the reaction dynamics and, albeit indirectly, on the energy and baryon density reached in nucleus-nucleus collisions. In the spring of 1992, the AGS produced the first beam of very heavy ions, more specifically a beam of 11.4 GeV/c per nucleon {sup 197}Au. This is an important step for the field since it gives a first glimpse as to how the reaction dynamics evolves as the mass and volume of colliding systems reach the largest value that will be available in the future. The authors have used part of the E814 experimental set-up to study the transverse energy distribution produced in Au induced collisions. These data can be compared to similar data obtained with lighter beams and thus provide for the first time information on how the E{sub T} distribution evolves with the mass of the system as one reaches very large systems.
