Hi,
I wanted to simulate transverse kicks along a beamline. I did it two different ways: (1) using a kicker element placed between two halves of a quadrupole and (2) using the h/vkick parameter of the quadrupole itself. Using the same transverse kick for each, I find different results (i.e. sddsplot -col=s,Cx -graph=lines,vary -split=page *.cen). I've attached example files.
I greatly appreciate any help resolving the discrepancy, or correcting my (mis)understanding.
Thanks,
chris

Chris,
I have a little trouble understanding your example, but I did a simple test and things work as expected. One point to realize (which is not stated in the manual), is that the kicks are applied at the entrance and exit of the magnet. I.e., the sequence is
Hence, you might see some slight differences from
Hope this helps.

Re: Kicker vs Quad Kicks
Thank you for the clarification. I was under the impression the kick happened once at the center of the magnet. This makes it clear.
Thank you Michael!
Thank you Michael!
