The growth rate of the hose instability is derived for a beam with Gaus sian r&dial profile, using the spread mass model of phase mix damping. It is found that the maximum growth rate of a co'nvecting wave packet is 49% larger than that derived for a beam with the Bennett profile, and the inverse group velocity (dz/dt) is also increased by about this amount. A general discussion of spread mass models is presented along with an explanation of the regurgitation phenomena seen in their numerical treatment.doi:10.2172/6535423 fatcat:yso55yrmmramrb6y3ratt7w3w4
