Combined function magnets?

Post by libov » 17 Oct 2013, 07:49

Dear Michael,

as title indicates: is there a possibility to simulate combined function magnets in ELEGANT?

Thanks in advance!

Cheers,
Slava

Slava,

Sorry I didn't see this sooner.

You can simulated combined function dipoles using SBEND and CSBEND. The KQUSE element allows simulating a combined-function quad/sextupole. The KQUAD and QUAD elements also support dipole steering fields.

I add a very basic question to this topic.
I verified that a dipole (SBEND with edge angles to make it RBEND, for example) with nonzero K1 behaves as a dipole+integrated quadrupole, where the quadrupole focusing happens to be in both transverse planes (neglect focusing from edges at this stage).

Question: is there any way to switch the quad focusing on in one plane only?
Thanks,
Simone

Simone,

There's no way to do that. I don't think there is a physical way to have fields in the body of the magnet that focus in one plane only. If you can tell me a bit more about what you are trying to model, I might be able to suggest something.
