Dear Didier,
When I use the BEND element, and I want to study the effect on a beam with varying energy, do I need to calculate the bending angle for the bend for each energy assuming the field to be constant, or do I not need to change the parameters of the BEND element?
Here is an example of how I define bend,
EDGE 3.282 21385.647 50.000 1e-06 1e-06 25.4 0
BEND 5.663869 21385.647 0.000 25.400 0 ; 2.475 BARC11 RBEND
EDGE 3.282 21385.647 50.000 1e-06 1e-06 25.4 0
When I change the beam energy, I expect the beam to go sidewise in the horizontal plane because of dispersion, but I am unable to see this effect.
Thank you
With Regards

Re: BEND
Dear Abhishek,
in BEND element the field is set according to beam energy defined in "Main" page. If you want to see the effect of deviation of a beam with different energies, you have 3 solutions:

in BEND element the field is set according to beam energy defined in "Main" page. If you want to see the effect of deviation of a beam with different energies, you have 3 solutions:
- Using the error definitions
- by entering a value "δW" in the "Twiss parameter" box accessible via the "Main" page
- By entering a second beam "Go to second beam" in the "Main" paga with a different energy. Then, in the "Charts" page, select the results of the first or second beam (this is clearly the solution I'll choose).
