This element simulates a multipole element using 4th-order sympletic integration. A single multipole order, n, is given. The multipole strength is specified by giving
|
| (99) |
where Bρ is the beam rigidity. A quadrupole is n = 1, a sextupole is n = 2, and so on.
The relationship between the pole tip field and KnL is
 | (100) |
where r is the bore radius.
