Michael,
all clear. Many thanks for your explanation.

I meant that the offset of the beam (with respect to the RF cavity) is used to compute the kick that (at this point) each slice gets. I badly expressed myself.

Thanks also for the very prompt reply, and have a nice day.

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 ...

Thanks a lot for your reply!
Kind regards,
Simona.

Dear Samira, I am not really an expert in the topic, but when I tried to do the same with a collegue using another code (only now I am trying with Elegant), we noticed that the quadrupole induced by the wiggler modified the optics, and the DA was strongly reduced. We rematched using the quadrupoles ...

Dear all, I am trying to use the function km2dds to compute the kick map from an undulator for the element UKICKMAP. If I want to build the kick map by myself it is clear that I have to generate a file which has (x,y,kickX,kickY) columns, because kickX and kickY will be two scalars for each couple (...

Dear Michael,
many thanks for your reply.
Kind regards,
Simona.

Dear moderators, I am trying to simulate a multi-bunch. I used this: &sdds_beam input = "distr_matched_ok.sdds", input_type = "elegant", center_arrival_time = 1, sample_interval = 5, reuse_bunch = 0, fiducialization_bunch = 0, !I phase with respect to the first bunch n_duplicates = 1, ! I duplicate ...

Many thanks for your reply!
Have a nice day,
Simona.

Dear Michael, I changed the distribution I applied the matchtwiss, and I repeated the full chain. Now I used the command: sddsmatchtwiss Linac1.out distr_matched.sdds -xPlane=beta=2.398316e+00,alpha=5.018045512606445e-01 -yPlane=beta=1.230487e+01,alpha=-2.328639e+00 When I analize the obtained beam:...

Dear all, I did some tracking simulations along a linac using bunched_beam. My line is a FODO with some RF cavities, so I computed the optics to have periodic beta and alfa, and all was working. Now I would like to simulate the same line, but using sdds_beam, because I can have a better representati...
