Re: sddsanalyzebeam Twiss parameters

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.

Re: sddsanalyzebeam Twiss parameters

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.

Re: sddsanalyzebeam Twiss parameters

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,

sddsanalyzebeam Twiss parameters

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...

Re: Slice dispersion?

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...

Slice dispersion?

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...

Re: Install on Ubuntu 21.10

Thanks again. I have tried to build the RPMs again by re-downloading the Build-AOP-RPMs file, and I still seem to be having problems. Instead now I get this error: Building SDDS RPM package. This may take a minute. Building target platforms: x86_64 Building for target x86_64 install: cannot stat 'me...
