Re: Simulation of transverse multi-bunch instability using the LRWAKE element
Dear Michael and all, I am studying short-range and long-range resistive wall effects in our ring. I used trwake element for calculating short-range effects and I saw the instability around 0.7 mA for single-bunch tracking in zero chromaticity. While using lrwake element for multi-bunch tracking, I ...

Re: Study of TMCI
Dear Abdurrahim, Your sdds file is a bit weird for me. The number which will be written in the first line of your txt file (before using the plaindata2sdds command) is the number of lines in your impedance txt file. This number must be equal to 2^n+1. If you fix this glitch, I think the elegant will...

Re: transverse wake implementation
Dear Michael and all, As I understood from the previous replies in this post, ELEGANT does the convolution for the bunch distribution defined in the code. So, the wake input file must be the point-charge (Green) wake function . Is that right? My second question is about transverse instabilities, in ...

Re: Help with generating sdds_bunch
Dear Michael, I have faced the same issue while I wanted to scan bunch current for multi-bunch tracking. I added reuse_bunch = 1 in &sdds_beam. Everything is OK, but it sticks in tracking the particles, writing: tracking 1400000 particles and nothing happens then. I attached the files for you. Any h...

Re: kquad and csbend
Dear Michael, Many thanks for the solution. It worked. Also, the same issue as mine exists in the ELEGANT examples. I think it would be beneficial to modify it too. Now, I realized a difference between the head tail modes appeared with the previous, less accurate method and the modified solution you...

Re: kquad and csbend
Dear Michael and all, I am trying to find the ILMatrix for different values of chromaticity of the lattice. I use the method of "ILMatrix from tracking" which is available online in ELEGANT examples. The primary twiss parameters shows that the values of chromaticity have been changed to the desired ...

Tracking with Broad-band Impedances
Dear Michael and all, I want to use broad-band impedance model for ring tracking. I set BROAD_BAND=1 in ZTRANSVERSE command and specified the resonators but I couldn't realize how to determine the plane (x/y) they belong to. Also, how can I figure out the appropriate bin size in this case? Any help ...
