Re: Local coordinates for 3D beamline layout

Dear Marcello, The script is included into the Elegant distribution as view3dGeometry program. This program can be also executed as a regular tcl-script once you comment the oagtclsh-specific parts on top of the script. Please see the attached example. In order to display beamline in 2d you can also...

Re: Bunch shape evolution in presence of longitudinal wake potentials

Dear Sara, I'm glad my example was useful! To understand the beam current calculation you can unfold this sequence of commands and do it step-by-step: exec \ sddshist $w -pipe=out \ -dataColumn=dt -sizeOfBins=[expr {$bin_size_ds/3.0e8}] -statistics \ -lowerLimit=[expr {$s_min/3.0e8}] -upperLimit=[ex...

Re: Bunch shape evolution in presence of longitudinal wake potentials

Dear Sara,

I did a similar tracking for the CERN SPS beam using Elegant.

Longitudinal dynamics
Please see the attached files for details -- I hope some of it could be useful to you.

Best regards,

Interactive plots of Elegant output in Jupyter

Dear colleagues, I thought this might be useful to other people as well: There is a bunch of interesting python packages for data visualization (bokeh, holoviews, datashader, ipyvolume, etc.) which produce nice interactive plots as html-files with some javascript. For example here is how to produce ...

Re: many-turn tracking with time dependent modulations

Dear Martin, I've recently made tracking simulations of bunch rotation (RF-gymnastics) in the SPS using Elegant. The attached example might be helpful to you since I'm using &modulate_elements with external file here. Best regards, Alexey ---------------------------------- SPS (LHC injector) has two...

Re: view3dgeometry

Sure, this script was drawing only RFCA elements.
The solution is simply to change this line of the script:
"if [string match "*RFCA*" $ElementType] {""
to
"if [string match "*RF*" $ElementType] {""

Re: view3dgeometry

Dear Charles, Could you post your lattice file or at least ".flr" and ".param"files? For me there seems to be no problem with RF cavities. Please see the attachment for the script (I use it in windows, so I've modified it slightly, therefore there's a chance that I've just removed the problem with m...

Re: ILMATRIX bug

Thanks Michael!

For my simulation linear_chromatic_tracking_setup turned out to be just fine, so this bug was not critical to me.

Of course ILMATRIX is more flexible, so I'll be using this element instead of linear_chromatic_tracking from now on.
