Excitation of the Kelvin-Helmholtz instability has been observed in a Q-machine when a sufficiently large velocity shear exists between adjacent layers of the plasma column. In an interpretation of this observation, possible effects of the finite ion Larmor radius and the collisional viscosity were neglected. The purpose of our study is to remove the first of these simplifications. With the finite ion Larmor radius included, the growth rate of the instability is computed for several values of the velocity shear and different e-folding lengths of the density profiles.
