Bunch duration along the beamline

[alexei_sav]

Dear Michael,

I have a simple beamline with several quads and alpha-magnet with 6D ensemble imported from ASTRA. How could I plot the bunch rms duration (that drives, e.g., bunching factor in the goal function) along the beamline and whether the St is correct parameter?

Thank you very much

Alexei,

St is the right parameter, giving as it does the rms arrival time at the observation location. You can get it by requesting the sigma output file from &run_setup.
