non spatial dispersion magnet design has been suggested to substitute the achromatic principle for improving the beam characteristics on target of the medical accelerator. The influences of reducing the distance between the target and magnet exit and the effect of changing injection angle of the magnet have been discussed to obtain the more compact deflecting magnet.
