Hello, 2 questions: 1/ In the version 2.23.3.4 of TRACEWIN, the phase advance plots in the GUI cannot be plotted anymore per lattice period. Can this option be re-inserted ? 2/ Can you make explicit the relation between the values Phase advance with space charge (deg/mm): σx, σy, σz. in partran1.out...

Dear Didier, Some questions regarding the treatment of cavities and errors ... (+ probably a bug in the manual ... ?) 1/ The DIAG_DPHASE and DIAG_DENERGY refer to a Delta Energy and Delta centroid Phase (on p. 57,58 in the manual) but it's not explicit to what reference these differences refer. Assu...

The 2nd request is about the checkboxes I highlighted in the attachement ... be checkboxes_as_parameters_in_noGUI.PNG so something like ./tracewin_noGUI.exe .... match_flag=0 match_partran=Y where match_flag= 0,1,2,3 refers to the kind of matching one wants to do and 0 is no matching ... Hope this c...

Dear Didier,

Would there be a possibility to pass additional parameters to the tracewin_noGUI.exe which select
1/ one of the three optimization algorithms ('Owner', 'Simplex' or 'Diff evolution') ?
2/ whether or not Matching is needed

Thanks in advance and kind regards
Jarno

Dear Didier, I tried to run the attached proton distribution with the lastest TRACEWIN version, but got a segmentation violation. I did get the message as you described (that the distribution cannot be fitted ...), but subsequently, there is a critical error and TRACEWIN crashes ... There is no prob...

Thank you !

Hello, Two questions related to the reading / creating .dst files 1/ I'm trying to read in a .dst file with an input file which has several fieldmaps. There is no compression on the .dst file. In the manual (page 39) there is a loop over Ne (number of elements), but it seems that inside the fieldmap...

Hello Didier, Is there a possibility to automatically perform the action 'Save table to file' (which one can perform manually in the Data tab of the GUI) when executing TRACEWIN with the 'noGUI' version (TraceWin_noGUI.exe) from the command prompt ? A bit similar to the flag 'Synoptic_file'. In the ...

Dear Didier, I have a question about the BEND element in TRACEWIN. We have a beam which is (on purpose) off-centered on a quadrupole. Thus, the quadrupole acts effectively as a combined function dipole. Trying to 're-interprete' the field index (-R/B.dB/dr) in this context, I came up -for this case-...

When using a toroidal electrostatic bender (parameter ne=3 in BEND_ELE), I get the following error message in Tracewin: >Sqrt error >From->[Elements]: Initialization of electric dipole: Element:6- >From->[Calc] : Ref particle transport Is the toroidal bender matrix elements implemented ? It is not p...
