Hello Michael,
I have confusion about the definition of R56. I can get the R56 from .mat file, which is an element of the transport matrix. Second, I can calculate it by particle tracking (.sig file): R56 = s56/s6*s6.
If I give some positive value of momentum chirp in the &bunced_beam, then I found different R56 from above methods. Technically, it seems correct because of <s*delta> corelation, but R56 is a beamline property so I would expect it to be same as obtained from .mat file. Could you please help me if I am mixing/missing something?

Aamna,
The relationship between s56 and R56 is as follows
so if you want to compute R56 from beam correlations, you need to use
--Michael
The relationship between s56 and R56 is as follows
Code: Select all
s56(end) = s56(beginning) + s6^2*R56
Code: Select all
R56 = (s56(end)-s56(beginning))/s6^2
