Hi, I have set up simulations in which I am collimating the bunch at a dispersive section in a bunch compressor, using the 'scraper' element. I would like to include the wakefield effects from the collimator in the simulations. Is this possible in elegant? I see that there is no mention of wakes for...

This has worked for me, thanks for the help!

Hi, I am having the same issue since upgrading from ubuntu 20.04 to 22.04. I have downloaded the RPMs for 22.04, but I get an error when trying to install the OAG rpm. The elegant and sdds RPMs installed without any issues. Here is the error: Unpacking of 'OAGTclTk-1.28-1.ubuntu.22.04.x86_64.rpm' fa...

Thanks for the help Michael!

I have attached BC2.W-INIT. The script I used to slice the beam and track the slices, is similar to what you provided here - viewtopic.php?t=1201.

Hi Michael,

I'm not using the -correctedOnly option, but in the above beta function plot betax and betacx are the uncorrected and corrected values from sddsanalyzebeam. Where both are larger than the twiss_output (betax.twi) values.

Here are the figures comparing twiss and sigma output compared to those from sddsanalyzebeam. It also won't let me attached the initial bunch distribution.

Thanks,
Adam

Hello, I am looking into how slice Twiss parameters evolve through a bunch compressor. I do this by slicing the beam and assigning each particle to a slice, then I use sddsanalyzebeam on each slice to get the slice beta and alpha along the bunch compressor. Typically I do this with a 2,000,000 macro...

Thanks for the explanation Michael! That makes a lot of sense and cleared that up. I have another question about the sddsanalyzebeam. As I mentioned above, I am slicing the beam and then I am using sddsanalyzebeam to track the evolution of the slice parameters for each slice along the bunch compress...

Hi all, I am looking into slice beam properties in a bunch compressor, so I have watch files along the lattice, some of which are at the centre of dipoles. I then slice these into longitudinal slices and use sddsanalyzebeam get the slice data for the bunch. In the output of these files there is hori...
