Chao, Sorry for not answering sooner. Sometimes the forum doesn't email me when new questions appear. I think the simulation is working as I expect it to. If I compute the change in kick angle from the coordinate WATCH files, I get a curve with the expected shape and height sddsxref FANKICKWATCH_2.W...

Samira, You can offset the x and y axes values by the integer tunes using the -offset option in sddsplot, e.g., sddsplot -col=nux,nuy fma_1.fma -graph=sym,vary=subtype,fill -split=col=diffusionRate -order=spect -offset=xch=7,ych=6 -scale=7.2,7.28,6,6.4 Looking at your lattice file, I noticed that yo...

Version 2026.4 has been released. The main improvement is addition of features that benefit long time-scale simulations, to avoid phase drifts due to rounding error. The manual has more details.

The problem is related to the way the BUMPER element aligns the time coordinates of the beam to the time coordinates of the waveform. In particular, it computes <t> for the particles and aligns that to t=0 in the waveform file. If you center your waveform t data about t=0, you should get the results...

It is hard for me to comment without having your files and without knowing how you generated the plots.

The examples file contains an example (straightDipoleModels/lgbend1) for BGGEXP and LGBEND, which may help.

Samira,

A skew dipole produces a vertical kick, so just use the YKICK parameter.

Minghao, 1. Elastic and inelastic scattering are single-particle phenomena. We can use Pelegant for the simulations to save time. 2. The run1.eslos file contains information on where scattered particles are lost. For each lost particle, it reports the coordinates at the scattering event (s, xp, xp, ...

Thanks for letting me know. A left-handed coordinate system is really odd.

Esraa,

There is no St field for marker elements, so you need to use Ss/c, e.g.,
It makes sense to have St for markers. We'll put it in the next release.

Version 2026.3 has been released, with several bug fixes and major changes, including * Inclusion of elastic gas scattering in 6D moments computations. * Propagation mode for coupled twiss parameter computation. * Built-in coupling and lattice function correction. * Expansion of spin tracking to mor...
