The z-pinch model is used to calculate finite Larmor radius effects of a plasma with a hot component plasma annulus. The equations are analyzed for layer modes and the finite Larmor radius stabilization condition is calculated. Stability requires k/sup 2/ rho/sup 2//sub h/ R..beta../sub h//..delta..> or approx. =1, where k is the wavenumber in the z direction, rho/sub h/ the hot species Larmor radius, ..beta../sub h/ the hot particle beta, and ..delta.. the thickness of the pressure profile. In addition a new instability is found, caused by the interaction of the precessional modes associated with inner and outer edges of the hot particle pressure profile.
