| Abstract | ||
| Optical properties of ion beam passing through the quadruple magnetic lens focusing system are discussed. The study included theoretical analysis using matrices representation to calculate the focal length, lens power, effective length and displacement (the bandwidth envelope) for Horizontal and Vertical plane. Results showed the increasing in effective length caused decreasing in focal length of the system for horizontal and vertical plane, the opposite action appeared with lens power. Furthermore the increasing in effective length caused decreasing in Horizontal displacement (beam envelope) for horizontal plane, the opposite action appeared for vertical plane. | ||
