Re: Third order dipole matrix
Posted: 25 Oct 2018, 10:26
Hi Michael,
All right, I'll stick with setting the edge effects to 1, then! I'll try to rememeber to set FSE_CORRECTION to 1 if and when I go back to using the symplectic model at some point. It also only gives me issues on BC1 and not BC2, but this might be because of the difference in K1 for the dipoles, as you mention, which are larger in BC1. In a sense, it's good that there was actually some sort of issue, since I was starting to feel a bit pushy.
Just for reference, I'm using double-achromat compressors, which are anti-symmetric (at least dipole- and sextupole-wise), like a dogleg.
I tried looking for TRANSPORT, it seems like it's available from AccelSoft, but not for free. I'll try to solve the third-order matrix in some other way then, as I have a whole paper that's almost done, where I need the total compressor U1666 value for computing stuff. Is there any future possibility for getting this matrix in elegant, or the option to have EMATRIX to third order?
