Torczynski, J R

In nuclear-reactor-pumped lasers, the fission-fragment heating is spatially nonuniform and as such induces gas motion. The competing effects of heating nonuniformity and thermal conduction on overall gas motion and laser optical behavior are examined, and a parameter is developed which categorizes the induced gas flow into three regimes. The effect of fission-fragment heating on perturbations in the gas density field is also examined, and a scaling relation describing the reduction of the rms density perturbation is developed in terms of the pressure rise produced by the heating. 24 refs., 5 figs., 1 tab.
