Hi，all

I wanted to simulate the beam in the extraction system in the cyclotron . I decided to use the OPAL-T to simulation the extraction system . So ,I have some problems in constructing elements in the beamline.

1).Firstly, how to load the background magnetic filed ? The background magnetic filed in the part of the main magnetic filed in cyclotron. Does opal-t have the element or some other ways can load magnetic filed in the arbitrary shape or our own magnetic filed data file ?

2).How to construct the electrostatic deflector? Can the RF cavities with 0 Hz take its place ?

Sincerely,

Dou
