TRWAKE on the beam
Posted: 26 Oct 2022, 06:19
Dear all,
I have a general question concerning the computation of the effect of the wakefield on the beam. I am presently running some simulations misaligning elements along a linac. I am comparing the results with another code, which is giving more pessimistic results.
A possibility pointed out by the developer of the other code is a possible different way of implementing the effect of the wakefield (transverse in this case) on the beam.
How does Elegant do this?
Does it the convolution of the bunch with the Green function, and after it computes a kind of "average offset" for the entire bunch or does it compute the kick of each slice along the bunch, and after (where the beam sees another wakefield) does use the different offsets to compute the effect on the beam?
Many htanks for any feed-back on this,
Simona.
