Hi All,

I have a rather complicated chicane for doing a stage of bunch compression. I can perform a standard optimization changing quadrupoles in the chicane to get different values of R56. Now I would like to simultaneously optimize on T566 as well but it's not in the %s.fin file. Any ideas how I can include T566 in my optimization?

Thanks,

MArk

Mark,

You can get access to the Tijk elements for optimization by setting matrix_order = 2 in &optimization_setup. This will give the final Tijk values. If you want interior Tijk values, use a MARK element.
