Abstract : A set of criteria is proposed for the onset of structure caused by the unmagnetized ion Rayleigh-Taylor instability in magnetically confined plasma expansions. R sub C, the critical radius at which structure can begin to develop, is independent of the magnetic field. There is a critical value of laser energy that needs to be exceeded for structure to develop. These criteria are consistent with available experimental data from AMPTE and the DNA/NRL laser experiment. A series of laser experiments recommended which will confirm (or refute) these criteria.
