Zero-length Multipole RF DeFlector from dipole to decapole
| Parameter Name | Units | Type | Default | Description |
| END_PID | long | -1 | If non-negative, highest particle ID to which deflection is applied. |
|
| GROUP | string | NULL | Optionally used to assign an element to a group, with a user-defined name. Group names will appear in the parameter output file in the column ElementGroup |

This element simulates an rf deflector with specified multipole content.
Assuming for simplicity that y = 0, the momentum change in the horizontal plane is
|
| (97) |
where k = ω∕c and px = βxγ. The deflection is
 | (98) |
where the approximation results from the fact that pz = βzγ also changes in order to satisfy Maxwell’s equations.
