Abstract

Numerical simulation using the r-z code GYMNOS shows the time evolution of the focusing and accelerating potential found in Post´s MIRRORTRON. Formed in a strongly anisotropic loss cone plasma, the transient potential is generated by the application of an additional local mirror field produced by a strap coil. The current rise time in the strap coil must be on the order to tens of nanoseconds in order for the plasma ions to remain inertially confined while the hot electrons respond to the local mirror force. The plasma density is low in order to facilitate the penetrations of the magnetic field into the plasma. Typical plasma densities in a MIRRORTRON are 10/sup 10/-10/sup 11/ cm/sup -3/ with electron temperatures in the hundred kiloelectronvolt to several megaelectronvolt range. The magnitude of the potential produced is on the order of the electron temperature. The formation of this potential peak is followed and test ions are projected through the resulting fields in order to evaluate the feasibility of using a MIRRORTRON as a heavy-ion accelerator.<>
