Elegant users forum

Dear Michael,

Is there a way to ask elegant to generate random errors on the bunched_beam centroid[0] values to set up random initial tranejctory values in performing trajectory corrections in a transferline, instead of the user preparing a set of random initial values and entering them one by one and run elegant?

I thank you in advance for your kind feedback and I am sorry if this was a non-appropriate (silly) question.

Ryutaro,

Yes, you can add a MALIGN (misalignment) element at the beginning of the beamline and then use the error_element command to add errors to it.

E.g., would impart 0.1 mm rms and 0.1 mrad rms errors in x and y, with a 2-sigma cutoff.

Dear Michael,

I thank you very much for showing me how my wished manipulation can be realized.
