Abstract

THIS REPORT PRESENTS THE STATUS OF EQUILIBRIUM AND STABILITY THEORY ON EXTRAP. THE CONSENSUS WAS THAT EQUILIBRIUM AND PARTICULARLY STABILITY THEORY SUFFERS FROM A LACK OF EXPERIMENTAL RESEARCH. WHILE IDEAL MHD THEORY REPRESENTS FAIRLY WELL EXTRAP EQUILIBRIUM PROPERTIES, LINEARIZED IDEAL MHD DOES NOT DESCRIBE STABILITY PROPERTIES. SOME EVIDENCE WAS PRESENTED FOR NON-LINEAR IDEAL MHD EXPLAINING EXTERNAL MODE BEHAVIOUR, AND NON-IDEAL AFFECTS PARTIALLY EXPLAINING INTERNAL MODE BEHAVIOUR. THIS IS A NECESSITY FOR ONE- AND TWO- DIMENSIONAL FULLY KINETIC APPROACHES TO ACCOUNT FULLY FOR THE LARGE LARMOR RADIUS EFFECTS OF A WEAK MAGNETIC FIELD AT THE AXIS AND SEPARATRIX. LESS AGREEMENT WAS REACHED ON WHETHER A LARGE RELIABLE MHD CODE SHOULD BE PROCURED FOR A SYSTEMATIC CLASSIFICATION OF EXTRAP IDEAL MHD MODES.
