Elegant users forum

Hello all,
I am trying to focus a beam of electrons with an energy of 250 MeV to a specific point in space using the elegant code. The initial beam size is 4 mm and the desired size is 0.001 mm. I am using six quadrupoles for this task.
I have tried using the &optimization_setup command, but I am not getting the desired results. Can anyone share their experience or suggestions on how to achieve this beam focusing using elegant code? Any help would be greatly appreciated.
Thank you!

I am also trying to do something similiar, it will be very helpfull!

Hello,

Thank you for reaching out. I would like to hear more about what you are trying to do and if you have any examples or code snippets that could help us both.

Hi!

I am studying about it. And from an example "Optimizing statistical Twiss parameters using quads" on this forum, i understood that i need first to determine the betax, alphax,... for the beam and use those as the initial values in the &twiss_output command. And after this optmize and goes on... But my doubt is about this initial values. I thought that this &twiss_output command would return me this the betax, alphax,.. parameters. So, now i do not know how that i will determine this parameters to use on &twiss_output command ?

Thank you!!
