It has long been expected that magnetic fluctuation driven ion radial
particle flux (< j_tildei||b_tilder>/eB)
in MST is large. Measurement, however, shows it to be small. Magnetic
fluctuation driven electron, and total charge radial flux, (<
have been measured using insertable probes. The magnetic fluctuation driven
flux for total charge is measured as being small, indicating ambipolar
particle flux, while for electrons it is measured as being large. This
is inconsistent with the measurement of magnetic fluctuation driven radial
ion flux. A robust upper bound can be placed on magnetic fluctuation driven
ion flux, leading to the conclusion that the electron and/or charge flux
measurments, both of which agree with prior well established measurements,
must be flawed.
