BEAM EXTACTION SYSTEM FROM DC60 CYCLOTRON

Abstract

The results of numerical simulation of the heavy ions<br />beam extraction system (A/Z=6&divide;12, W=0.35&divide;1.77<br />MeV/amu) from the DC60 cyclotron are presented. The<br />parameters of the extraction system elements<br />(electrostatic deflector and focusing magnetic channel)<br />and diagnostic elements are chosen. The experimental<br />extraction efficiency of 14N2+ and 84Kr12+ beams<br />is equal to 60&divide;65% with intensity 1.5&divide;2.5 &mu;A.IMP;Chinese Academy of Science
