Thank you for your fast answer. I think I understood where the issue came from, thanks to your comment that the space-charge cannot be taken into account when calculating the acpetance. Indeed, when I eliminate the space-charge forces by setting the current to zero, the acceptance is calculated corr...

I'm having trouble calculating the beam acceptance of a beam along a cavity. From an initial distribution, I run the simulation and I get the output phase space, with which I calculate the acceptance with PlotWin from the method explained in the Manual (Acceptance calculation using TraceWin and Plot...

Sorry because I think I made a mistake when launching the simulation and I had not loaded the distribution properly. Anyway, when I export the output beam from Chart->Output->Save (to txt) the mass that appears in the header corresponds to the mass of the main beam that is taken as reference. Theref...

When a second beam is defined, the mass shown in “Beam data” of the main tab is not well defined. Despite correctly defining the mass of the ions, the rest energy data in “Beam data” remains the same as for the main beam. This affects the results, since when the phase space is exported to ASCII file...

I noticed that when you modify the Kinetic Energy parameter in the 'Input Main beam parametrers' tab once you have imported all the beam parameters from an external file, the energy of all the particles changes to exactly the same value. In this way, if the input distribution had a certain energy di...
