Re: RF potential by double RF system

Hi Michael, First thanks a lot for your kind reply! I'll try to vary the phase of the main RF cavity and the voltage of the harmonic cavity following your kind suggestions. However, In still don't understand why the RF settings should be different. In the two test ("damping=1,qexcitation=1" or "damp...

RF potential by double RF system

To whom it may concern, Hi! It's Haisheng Xu who is using elegant in the study of double RF system. There was a problem in using double RF system to generate 'ideal-flat' RF potential. Wish to get your help! The details were described as follows: I first calculated analytically the voltage and phase...

Re: Question about having a fiducial bunch in a ring with bunches from sdds file

Hi, Michael and all, It's Haisheng Xu. First of all, Michael, thank you for the example scripts which are very inspiring! I'm also trying multi-bunch simulations, and struggling with the beam preparation step... The purpose of mine is to study the transverse high-order modes induced coupled-bunch in...

Re: Version 35.0.1 writing .sdds files

Hi, We compiled the elegant version 2019.1.1 and sdds version 4.1 from the source code on our Scientific Linux Release 6.9 system. However, we still have the same problem. May I ask that whether there is any special attention has to be paid in the compiling process? Look forward to your kind help! R...

Version 35.0.1 writing .sdds files

To whom it may concern, Hello! I'm Haisheng Xu from IHEP who is using both elegant and Pelegant in my work. Recently, I found a problem after updating the code to version 35.0.1. Wish to get help from you! The problem is that sometimes the data in .sdds output files are not able to be read by the sd...

Re: bunch-by-bunch feedback simulation

Hi Michael, Thank you very much for the kind and detailed reply! I've got clearer understanding about the unnecessary 'pi/2 phase advance' after reading your reply and the reference you mentioned. I tried to use a 8-turn filter in the simulations and do see the feedback stabilizes the beam under som...

bunch-by-bunch feedback simulation

Hi Michael, I'm learning to simulate effects of the bunch-by-bunch feedback system in the storage ring by the example ".../examples/multibunchCollectiveEffects/APS-24Bunch-CBI". However, I'm confused by the settings of the xpickup, xdriver and ypickup, ydriver in the "lattice.lte" file. My understan...
