Dear Didier, Currently, I copy two files, tracewin.out and partran1.out, after each run during batch mode. With these two files, I can plot the envelopes using Matlab. There is also a much larger file containing the dynamics of each of the particles, which you can plot the phase space etc in the GUI...

Dear Didier,

Is there a way to view plots in PlotWin or the TraceWin GUI after running a simulation in batch mode?

Best regards,

Dear Didier, Is it possible to perform matching in envelope mode to optimize RF phase when simulating a CW input beam? The answer "no" seems to be obvious but when I run a CW beam through an RF gap or w_p_limit, TraceWin seems to be able to identify the synchronous particle as the "zero phase" parti...

Dear Didier, Thanks a lot. In general, when you upgrade TraceWin.exe, is TraceWin_noGUI.exe also being upgraded? I use a script to run batch using TraceWin_noGUI.exe through cmd, and then copy two files: tracewin.out and partran1.out. Sometimes that two files are not available for some parameter val...

Dear Didier, That fixes the problem. But it created another problem. I don't know exactly what it is. A model that I can run without problem with the last version now cannot run with the new version. The complain is related to variable: drift 30-(xa11-40) 10 I guess it is related to the "11" in the ...

Dear Didier,

I believe there is a bug in the variable command. Please see attached model for an example. In the model, when both "xa1" and "xa10" are declared, "xa10" will have a wrong value. If you comment out "xa1", then "xa10" will be correct.

Dear Didier, My understanding to my first example is that: drift 10 10 diag_dsize3 11 5 drift 10 10 diag_size 11 0 0 20 diag_dsize3 11 5 I am demanding a phase spread dP(z=20)=20 at z=20. At the same time I am demanding the difference in phase spread to be dP(z=20) - dP(z=10) = 5. So equivalently, I...

Dear Didier,

If I understand the user manual correctly, my second example is also for phase spread. Please see attached snapshot.

Best regards,

Dear Didier,

Is the example below the correct way of using diag_dsize?
drift 10 10
diag_dsize3 11 5
drift 10 10
diag_size 11 0 0 20
diag_dsize3 11 5

Is the above the same as this example below?
drift 10 10
diag_size 11 0 0 15
drift 10 10
diag_size 11 0 0 20

Thanks and best regards,

Dear Didier, Could you please provide an example of how to use DIAG_DCURRENT? I would like to optimize a section such that there is no current/beam loss. According to my understanding to the description of DIAG_DCURRENT, I came up with the below, but didn't work: DIAG_DCURRENT 22 0 xxx ADJUST 22 1 x...
