Hi Didier,
I have a couple of questions regarding the synchronous phase:
1. I've noticed that there is a tiny difference between the set input synchronous phase (-45°) and the actual synchronous phase of the first cavity (44°).
This is not immediately a problem, but I'm wondering where the difference comes from.
2. Secondly, I've noticed that the second cavity in my period always has a slightly higher synchronous phase,e.g. -44° for cav1 and -44.3° for cav2. Why is that? which rule in your algorithm causes this? I'd expect that following the const. longitudinal/phase acceptance would result in a continuous decreasing sync. phase...
3. When I apply the equation for const. longitudinal acceptance myself I get slightly different sync. phases for subsequent cavities, e.g. for the first cavity in the second period, I find -42.8°, while GLW finds -43.3°. (Proton energy at the LINAC entrance = 16.6 MeV, and at the entrance of period2 = 17.2 MeV).
If needed, I can send you the project files in a private message.
Cheers,
Lennert

Re: synchronous phase difference
Dear Lennert,
Points 1 and 2 were definitely caused by a bug that I recently introduced by mistake and have now fixed. You can upgrade your software. This will probably fix point 3 as well, but you'll have to let me know.
Regards,
Didier
