Abstract

Particle trajectory calculations were conducted based on TS-4 magnetic probe data in the R-Z plane assuming axisymmetry. An acceleration mechanism for electrons trapped in a merging Spheromak during the formation of a FRC that is causally connected to the out of plane E _φ field during reconnection is found. The energy profile resembles a stair step like motion as the electron is accelerated from the reconnection E field on multiple passes confined to constant magnetic field lines.
