The issue of simultaneous longitudinal and transverse particle propagation stability in a linear ion accelerator channel based on combined RF-focusing is investigated. Values for RFQ field gradient to provide transverse propagation stability for all the particles in an acceleration mode are calculated. It is also shown that electrical strength of the electrodes influences the gradient value. Much attention is given to modeling of an accelerating-focusing channel which provides the minimal growth in beam emittance.
