MAGNETIC QUADRUPOLE DESIGN CONSIDERATIONS,
Abstract
The design of a quadrupole lens based upon an ion optic study is considered in terms of a parameter PHI for quadrupole lenses related to the magnetic field gradients and ampere turns. Figures showing particle trajectories through a quadrupole doublet parameterized in terms of this dimensionless quantity PHI are given. Since the desired trajectories are usually known, PHI may be found directly from the figures and related to the current in the quadrupole for a given le energy and a given quadrupole design. A Fortran program is included for calculating the matrix elements describing the particle trajectories. (Author)
