Recently first experiments with truely heavy ultrarelativistic nuclei took place at the AGS. Measurements of the distribution of transverse energy E{sub t} were performed as a function of the mass of the system by the E877 collaboration. Compared to light systems a large increase of transverse energy production is observed for Au+Au along with a narrowing of the distribution of transverse energy in space (pseudo-rapidity {eta}). Analysis of the observed scaling with mass number shows that dE{sub t}/d{eta}{sup Au+Au} = (197/27.5){sup {alpha}} {center_dot}dE{sub r}/d{eta}{sup Si+Al}, with the parameter {alpha}{approx}1.2. This first direct measurement of {alpha} demonstrates that a Au+Au collision is not a superposition of independent nucleon-nucleon collisions (where {alpha} = 1) but involves many more collisions (197{sup 1.2}/197{sup 1.0} = 2.9!) This and other AGS results will be discussed in the context of high baryon and energy density creation at AGS energies.
