Dear Romuald, Thank you for the quick response! You are right, I would indeed like to apply the "transcell rules" to the cell before the flat section. I only manage to do this if I proceed directly to the fringe field. Your explanation confirms my suspicion that the combination of a transcell and a ...

I am attempting to generate a .vane file from the .dat file with the2termsflag. However, I struggle to get the end profile geometry correct. The lattice needs to end with a transition cell, followed by a flat m=1 cell and a fringe field. Unfortunately, I never succeed in the proper combination of bo...

Dear Didier,

Thank you so much for clearing this out for us. This really helped us understand the problem and improve our simulations.

Cheers,

My simulation setup includes an ion source, a LEBT, and an RFQ. While running the simulation with Partran and Toutatis, I observed a discontinuity in the longitudinal emittance within the RFQ. Specifically, the emittance drops to a lower value midway through the RFQ and then recovers near the end. I...
