Hello Michael, I try to look at the source codes, and find the calculation for relative velocity as follows in several places (such as, in code multipole.c and csbend.c ): -------------------------------- beta0 = p/sqrt(sqr(p)+1); ------------------------------- If I understand correctly, here, $bet...

Hello Michael, To define a canonical kick element, such as KQUD and KSEXT, we need to provide the N_KICKS parameter. What does this parameter exactly mean? For example, if N_KICKS = 18 and INTEGRATION_ORDER =4, does this mean we split the element into 6 slices first, and then apply the 4th order sym...

Thanks, Weiming and Michael. I am looking forward to the release of the genetic optimization.

Attached are the files I use to generate twiss parameters. Thanks!

Hi Weiming Guo, Thanks for your example. In the example, you are using dnux/dp and dnuy/dp to target the desired chromaticity. I am just curious why you don't use the linear chromaticity driving terms h11001 and h00111? I noticed that in the twiss parameter output file, the driving terms h11001 and ...

hello Michael, Thank for the explanation. We are also interested in the same kind of problem. Could you post an example using resonance driving terms to improve the dynamics aperture? You mentioned the genetic optimization works better than driving terms optimization. May I ask for your genetic opti...
