Tracking through offset quadrupole with CSR

Post by jrowland » 10 Nov 2009, 06:40

Hi

I'd like to model an off-axis quadrupole used as a bending magnet with CSR. Is it possible to use CSRCSBEND with a K1 term and FSE to turn off the dipole field but keep the reference co-ordinate bend?

Thanks

James

James,

Can you tell me what you are trying to accomplish with the simulation? Is it to model the CSR from a misaligned quadrupole?

Hi Michael

It's an offset quadrupole being used as a bending magnet in the NLS linac. After discussion I think we can add a K1 component to the CSRCSBEND and get the right additional focussing for off-axis particles.

Thanks
