Description

Critical lengths are found for the stability of mirror-confined plasmas to the convective loss-cone mode (driven absolutely unstable by wave reflection from the mirror throats), using the straight-line ion orbit approximation. Electromagnetic effects are included. For fusion reactor parameters, the critical length in ion Larmor radii is roughly 10β/sup -1/2/ (where β is the ratio of plasma pressure to magnetic pressure). Taking the drift cone instability into account, no mirror fusion plasma can be linearly stable unless there is some warm plasma (about 1%) in the loss cone
