Experiments and simulations on the possibility of radiative contraction/collapse in the PF-1000 plasma focus

Experimental studies of discharges in the plasma focus facility with neon filling and respective numerical simulations employing the radiative Lee code are reported. The pinch currents exceed the Pease-Braginskii current, which indicates that radiative losses are larger than heating and that contrac...
