Ah, in projection you mean, I thought you meant the ions moved only in that plane because you wrote "_outward_ radially", in fact it's only outward for a short distance and then inward for most of the ion flight time. > In that > plane the direction of flow is radial only except when acted upon by > the armature, which action provides a tangential motion. Yes I agree. The projection of an ion's trajectory in that plane is no more a straight line when it's attracted to the rotor.
