Dear Vadim,

Thanks for the help and suggestion. Yes, it's worked perfectly after the changes.

Dear Vadim and all, I try to use shifted quadruples+normal quads for correcting the beta beating. I added my shifted quads in the element list, but when I run for the beta mode correction I faced with the error as below: error: column bqf4_1L not found in file /net/phase/store/users/sara.dastan/Eleg...

Dear all,

In the instruction of the LRWAKE, there is something that I don't understand. Why the XFACTOR should multiply in longitudinal wake and ...? Is it true or it is just a mistype? Thanks in advance.

Dear Vadim and all, I updated my Ubuntu to the 22.04 version and update my elegant too, but now when I want to run the attached previous example, in the third step which is the correction of the beta parameters, I get this error which I don't have any idea what is the origin of it. Would you mind yo...

Dear all, I tried to do tracking for beam loading calculations using the RFMODE but it seems that I faced the same problem that Alexis faced, however, I didn't use charge in RFMODE. 3 of 10000 particles outside of binning region in RFMODE RF_H #1. Consider increasing number of bins. Would you mind i...

Dear Vadim,

Many thanks for your very kind help and detailed solution. As, you suggest I used local quads for twiss correction and global ones for correcting tunes. It seems that every thing is good and perfect now.

Dear Vadim, I tried to correct the superbend lattice without using inverse bends (BQF1, BQF2, BQF3, and BQF4), and instead use sbb1a and sbb1b in the 4th, 8th, and 12th cells. I assumed that in this case, I should make changes on the makeElementListFile , and I can make the element list, but by usin...

Dear Vadim,

It is amazing. Thanks a lot for the complete explanation of the procedure of correction and the details of it. It is also great that I understood what was the origin of the error that I faced. I did it and as you said the correction looks perfect.

Dear Vadim and all, I have been trying to correct the Elettra lattice by considering a superbend magnet in the 3 cells of the lattice (cell4, cell8, and cell12). In this case, the measured lattice is the lattice with superbends and the ideal lattice is the one without super bends. I thought that may...

Dear all, I used Elegant for beta beating and coupling correction in the presence of errors with the wonderful and great support of Vadim Sajaev and I think It could be helpful for others so I share the process and steps here. The method is precious and much faster than the simplex method. I try to ...
