Dear Didier,
It works!

Dear Didier： Thank you very much for your answer，I may not have been clear about my question. In my question, lattice 3 hand lattice 4 have the same cell1, but the cell2 of lattice 3 is freq 325 lattice 3 1 DRIFT 85.13 20 0 0 0 FIELD_MAP 70 345.1 0 20 0.572458 1 0 0 solenoid 0 SET_SYNC_PHASE FIELD_M...

And the frequency of my beam is 162.5MHz

Dear Didier：
I have question about meaning of phi_Rf and Superpose field maps， and I encountered some problems， the question is long , So I put it in PDF.

Dear Didier, Thank you very much for your response. I now understand the issue. However, I still have a question. According to the display in TraceWin, the unit of beta should be "mm/π.mrad", and after integrating the phase shift, the unit should be "π.rad". In the past, I understood this as 1π.rad ...

Dear Didier, I have a question about phase advance. I used a set of test lattice which consists of two periods, each containing a solenoid and a drift. My solenoids are very short, so the betax of the beam in the solenoid remains almost constant at 0.59 mm/π.mrad. The lattice is as follows FREQ 162....

Dear Didier,
Thank you for your reply,

Dear Didier, I have a problem that the field map only tells me the electromagnetic field at specific positions. However, the actual position of the particle may not be exactly on these points, and I assume that interpolation is used here. Different interpolation methods may yield different results, ...
