CEA Codes forum

Dear Didier, Please refer to the previous conversation in this post. The problem was solved at some point of time. But it appears to be problematic again. For example, TraceWin would randomly quit (GUI disappeared) if I use the following variables naming: variable pa1 1 variable pa2 1 variable pa3 1...

Dear Didier,

It seems that the codes still randomly breaks when I have variables running from xa1 to xa10 and above. The codes is perfectly fine with variables up to xa9. I believe the codes don't break randomly, but I cannot find the pattern.

Dear Didier, Recently I attempt to run codes from a few months ago without any change, diag_size provides very different and incorrect results. I fixed my codes by changing it to diag_size_fwhm. Of course it is slightly different but it is what I expected. To be specific, the problematic code is "di...

Dear Didier, Currently, the lattice command requires the same number of elements for all successive focusing periods. Quite often it is practically difficult to fulfill this requirement. Would you kindly consider adding a version of the lattice command that counts only the quad elements. It would be...

Dear Didier,

Is the following a valid combination? Does it target at 0.5mA at the location of the diagnostics?

Input beam current = 1mA
diag_current 99 50 0 1

Dear Didier,

So in the case of zero current, what does the "Ib" means in the statement "DIAG_CURRENT N Ib"? Is it the number of particles?
Also, does the same apply to DIAG_DCURRENT?

Dear Didier,

Ah! I only realized that there are two save buttons after you mentioned it. I kept pressing the project save button and mistakenly hoped it would save the .dat file. Problem solved.

Dear Didier, and other colleagues, Can you command on the difficulty with set_sync_phase when the voltage is too high relative to the input beam energy? Is it a pure mathematical and optimization difficulty? Or is it physical so that one should avoid when it happens in the model? Best regards, Wai-M...

Dear Didier,

I am running Version 2.21.0.12 on Windows 10.

Dear Didier,

The "save" icon doesn't seem to be effective. The .ini project file and the .dat layout file do not save until I close the GUI and choose "yes" to save.
