A series of experiments has been performed to investigate the effect of unidirectional beam particle rotation on the resistive hose instability. Using the 4 MV, 100 kA, IBEX accelerator in a foil diode configuration, hose growth for hollow, partially hollow, and non-rotating Bennett profile beams was investigated. It was found that partially hollow, rotating beams were most stable. In particular, they were more stable than non-rotating Bennett profile beams both in terms of the growth rate in per cm and in the growth per betatron wavelength. The observed reduction in instability growth rate per betatron wavelength over Bennett profile beams was a factor of 2.5. Stable propagation for >6 betation wavelength (the full experiment length) was observed in some shots where the beam was well aligned. Broadened return-current profiles and long plasma decay times were also observed, consistent with our present understanding of high current mode propagation.
