How to correct beam trajectory by moving quads?

Post by WEI-HOU » 15 Jun 2023, 18:54

Hello,

In Elegant simulation, is it possible to correct the beam trajectory by moving quads, such as changing DX or DY of quads, instead of applying HKICK or VKICK?
Thank you.

Wei-Hou,

Unfortunately, there's a bug that affects this feature, so it won't work in the present release. I'll fix it in the next release.

For now, you can ask elegant to use the HKICK and VKICK parameters, as in

Code: Select all

Q1: QUAD,HSTEERING=1,VSTEERING=1,...
You can then convert the values using, e.g., DX=HKICK/(K1*L).
