Re: Inconsistent beam emittance values from GUI tools

Dear Didier, Thanks; this discrepancy has now been resolved. Although I was running the code using Partran, the default output "Results from" selected in the "Charts" menu was "Envelope". After changing this selection to "Partran", the four workflows described above give consistent results. In the p...

Re: Inconsistent beam emittance values from GUI tools

Dear Didier, My previous post was a bit premature. I still see the emittance discrepancy, when running from a clean working directory, but only when multiparticle tracking using Partran is selected. Unfortunately, I have a very large lattice, and the effect accumulates over a long portion of the bea...

Re: Inconsistent beam emittance values from GUI tools

I was able to recover agreement among the four workflows shown previously. This happened after I manually deleted any old output files from within my working directory. It's likely that one or more of the postprocessing tools was accessing output files from an older run with different parameters. It...

Inconsistent beam emittance values from GUI tools

Dear Didier, After running TraceWin on a linac input file, I see two different sets of values for the final normalized x-emittance at the exit of the transport. The difference is large (more than a factor of 2). (The discrepancy exists for the other emittances as well as the beam sizes in each dimen...
