Dear Didier,

Thank you so much for your wonderful suggestions. If I use "MULTIPOLE"(for solenoid) and have satisfactory results, how can I decide the aperture, thickness and length of my real solenoid? Could you please tell me how the fieldmap of "MULTIPOLE" is created ?
In my research, we need to decide the actual size of the solenoid.

Looking forward to your reply.

Regards,
Jie Li

Dear Jie Li,

The mechanical dimensions of your solenoid will depend on your needs in terms of focal strength, integration space limit and obviously beam size, I really can't help you on these points.
How is the field map made, this is simply based on the usual analytical expression of the magnetic field in a solenoid

Regards,

Didier
