Ion-optics systems of multiply charged high-energy ions for high emittance beams

Methods are presented for the calculation of high-emittance ion-optics systems based on magnetic quadrupole lenses for beams of protons and heavy ions with energies from 1 to 10 MeV/nucleon. The strong focusing of the system makes it possible to form beams with linear dimensions less than 0.1 mm. The system for increasing the deflection triples the deflection angle of the beams during scanning. The systems are designed for use with beams from the cyclotron at the A.F.
