Dear Didier, Recently, I’ve been working on emittance calculations. I found that my results for the x-x′ and y-y’ planes match well with TraceWin, but the emittance in the z-z’ plane is always different. After reading the documentation about the transformation between 𝜙-𝑊 and z-z’, I suspect that th...

Dear Didier： When I use TraceWin for error simulation, I use density to analyze the results，I am not quite sure what Z refers to when using Z density and density level. I hope you can help me clarify this. For X, Y, and R, I understand them as the beam's displacement in a plane. I don't know how Z i...

Dear Didier:
I have download the new version, and the terminal doesn't show "QProcess: Destroyed while process ("pscp.exe") is still running". And the waiting time went from 20s to 5s. Is this normal?
Thank you very much.

Dear Didier: When I use the nogui.exe, it always takes a long time, and then it prompts: Qt: Untested Windows version 10.0 detected! QProcess: Destroyed while process ("pscp.exe") is still running. However, after waiting for about 20 seconds, it still produces the correct results. Is this due to com...

Dear Didier: When I conduct error analysis, if I select "multiparticle," I can find "Error_Datas.txt_0." However, if I select "Envelope," I cannot find this file. I want to know the error values generated each time. Is there something wrong with my settings, or does the "Envelope" option not have th...

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.

Best regards,

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 ...
