Kerr cell photographs through a mesh anode have shown growing flute patterns on the interior luminous surface of the plasma cylinder. These appeared when the pressure of the enclosed axial field reversed the initial inward acceleration, as is expected for the accelerational hydromagnetic analog of the Rayleigh-Taylor instability. The measured growth rates ranged from about one- half to the full value predicted by simple theory. This agreement extended over a range of operational tube conditions. As predicted, application of an interior stabilizing field from a central wire erased the visible fluting. (auth)
