Discrepany in R26 and R56 for transversely offset KQUAD
Posted: 29 Nov 2023, 06:55
Hi Michael,
I am creating a beamline with an DX-offset quadrupole to induce some fine-tuned dispersion. But I noticed when I look at the R-matrix for the offset quadrupole there is no effect on the R56. Additionally when I cross-reference with another particle tracking code (Bmad) I get completely different R56 and R26 as well. I did try toggling all the parameters I could find in the KQUAD element to "turn-on" the R56 but with no luck.
Would you have any insight on this matter? I've attached a sample file.
Thanks in advance!
