Numerical modelling of an end-plugged theta pinch
Description
Analytical and numerical studies of an end-plugged theta pinch are described. The analytical mode treats the ablated plug plasma in the quasistatic limit where radiation losses balance energy flowing from the main plasma. This model is used to calculate the enhancement in energy confinement due to an ablating end plug for various plug species. The numerical model employs a one-dimensional, time-dependent magnetohydrodynamic code. Results of calculations simulating the Scylla IV-P end-plugged theta pinch experiment are presented. The calculations achieve reasonable agreement with experiment except for certain notable discrepancies, believed to spring from two-dimensional effects
