Experiments have been initiated into the confinement and extraction physics of high charge-state ions in an ECRH mirror plasma. ECRH mirrors are well suited for producing high Z ions because the hot electron temperature (>100 keV) is sufficient to fully strip heavy ions. The charge state distribution (CSD) of the ion endloss and the ion endloss temperatures have been measured using a time-of-flight analyzer. The CSD of the confined ions has been measured using a VUV spectrometer. Applying ICRH to the plasma was found to lower the Z/sub eff/ of the confined ions while raising the Z/sub eff/ of the extracted ions. The experimental results are compared to theoretical models which include Pastukhov, flow, and spatial-diffusion confinement times. 12 refs., 16 figs.
