Plasma energy confinement in conventional mirrors with externally heated electrons

By means of a 2-d, multi-species, Fokker-Planck code, it is found for conventional mirror reactors that heating of the electrons from an external power source leads to a decrease in Q. Likewise, for mirror plasmas such as 2XIIB, electron heating does not improve the total energy confinement because of additional losses associated with quasi-linear stabilization requirements.
