Dear Didier,

I would be happy if TraceWin could be extended with a new element: "DIAG_EMIT_100", for optimizations with the 100% emittance ellipse of a distribution.
This could perhaps even be generalized as "DIAG_EMIT_N" with N as the percentage of the corresponding ellipse (like it's already existing for 99% with DIAG_EMIT_99). This would allow users to use this as they wish without having to code their own diagnostic element.

Thanks in advance for your help and best regards,
Malte

Dear Malte,

Looking at how to answer your request, I realised that this already exists. In fact, the manual is incomplete (I just amended it) and finally DIAG_EMIT_99 is already defined as DIAG_EMIT_NN.
So, 99% fraction has to be set in “Multiparticle” tab-sheet, then go to “99.XX% emittance and halo”,then select the fraction you want. This choice is used for the "XX.XX% Emits" output chart, but also for DIAG_EMIT_99.

Regards,

Didier

That's great, thanks!
