Abstract : The completed major parts of the three year program are upgrading of the plasma focus machines of the Stevens Tech laboratory to higher powering energy levels W1>20 kJ and W2>100 kJ, test of the scaling laws relating fluence and spectral characteristics of the ion cluster and supercluster emission to W, clarification of the leading physical processes which are characteristics of the plasma source of ion clusters and of superclusters with mass/charge ratios greater than 10 to the 12th power a.u., and data acquisition and evaluation with new methods, specifically addressing ion clusters and related exotic plasma states. The source of ion clusters and of superclusters, as well as the source emission, are examples of exotic plasma states. These include, but are not limited to, states of self-field-dominated plasma where the self-field energy is of the same order of magnitude of the particle kinetic energy. The particle motion is self-organized from the <l0(exp-5) cm to the >2 cm scale, with the bulk of the kinetic energy stored in the organized motion exceeding the thermal energy. (AN)
