摘要:
Four different thermal conduction models have been used to calculate the critical density limits in Ohmically heated tokamaks using the electron and ion energy balance equations. The results are compared to experimental density limits for a variety of Ohmically heated tokamaks.

摘要:
Two‐dimensional hydrodynamic simulations show that small diameter laser spots burn through flat foils considerably faster than larger spots. The physical mechanisms are (1) more nearly spherical divergence from the smaller spots which allows the debris to rapidly convect radially away from the small volume of laser heated plasma and (2) a variation on thermal self‐focusing in which light is refracted into this volume, increasing the local heating rate.
