- Abstract
- Computer simulation and optimization have been carried out of ion transport line intended for focusing and deflection of ion beams generated by the cyclotron. Ion transport line includes five magnetic quadrupole lenses and electrostatic deflector. In order to increase amplitude of deflection the principle of amplification of deflection based on divergent action of quadrupole lens is employed. The dependence of ion line transmission on the coefficient of deflection amplification has been studied and focusing modes are found which are characterized by maximum transmission. The influence of aberrations of deflection is investigated.
