The theory of unfavorable curvature-driven instabilities is developed for a plasma interacting with a hot electron ring whose drift frequencies are larger than the growth rates predicted from conventional magnetohydrodynamic theory. A Z-pinch model is used to emphasize the radial structure of the problem. Stability criteria are obtained for the five possible modes of instability: The conventional hot electron interchange, a high-frequency hot electron interchange (at frequencies larger than the ion-cyclotron frequency), a magnetic compressional instability, a background pressure-driven interchange, and an interacting pressure-driven interchange. The effect of F.L.R. stabilization on the low-frequency modes (less than the ion-cyclotron frequency) will be discussed.
