Twiss Matching
Posted: 16 Jul 2020, 05:40
Hi Michael,
I have been trying to match 6 parameters at the end of the beam line (betax, betay, alphax, alphay, etax and etaxp). I am using 6 quadrupoles . I tried many times with different starting values (random number generator for initial k value for each quad) but ELEGANT was not able to find the solution (although there is a range for the tolerance in sene constraint).
Since there are 6 parameters for matching, with 6 quads I expect a solution for my problem. Is that true or it doesn't work for some cases?
I was wondering if there is a better way to find the solution.
Thank you in advance,
Farzad
