Thepropagation of an intense relativistic electron beam through a gasthat is self-ionized by the beam's space charge and wakefieldsis examined analytically and with 3D particle-in-cell simulations. Instability arisesfrom the coupling between a beam and the offset plasmachannel it creates when it is perturbed. The traditional electronhose instability in a preformed plasma is replaced with thisslower growth instability depending on the radius of the ionizationchannel compared to the electron blowout radius. A new regimefor hose stable plasma wakefield acceleration is suggested.
