Diag_XXX command inside field map

[shliu]

Hi Didier,

Could the Diag_XXX command be located inside field maps? Maybe the format like:

superpose 0 0 0 0 0 0
field_map 0070 1000 0 50 1.0 0 0 0 Quad1 0
superpose 800 0 0 0 0 0
field_map 0070 1000 0 50 -1.0 0 0 0 Quad2 0

How to set beam size at location 900 mm?

Hi Shliu,

Have a look on the SHIFT_IN_FIELD_MAP command in manual, especially dedicated to that.

Thank you for the reply!

What if the field map is in a bending section? For example, two dipoles bending to the same direction and one quadrupole between them for achromat consideration, and I want to set beam waist at the middle of the quadrupole. The 3 field maps are superposed.

I tried the SHIFT_IN_FIELD_MAP command but seems it doesn't work in my case. So, do you have any suggestions?

BTW, is there a way for plotting beam distribution in a superposed field map?

Kinds,
Shliu

Dear Shliu,

Yes right, SHIFT_IN_FIELD_MAP didn't work in field map bending trajectory.
This feature has been added in the last TraceWin release
