Re: ramping with sextupoles
Dear Michael, I compared two cases of 1 Hz and 3 Hz for booster ramping. In case of 1 Hz horizontal emittance and energy spread approach to equilibrium values i.e., at top energy 2.5 GeV while at 3 Hz they are lower than this. Do you have any comment on this? Many thanks in advance and Best regards,...

Re: ramping with sextupoles
Dear Michael, Many thanks for reply. I changed my lattice. By Ramping at natural chromaticity, 165 particles lost. After setting K2 parameters in dipole and in local sextupoles to reach +4 chromaticity, again I repeated ramping but in this case all of the particles are lost. I tried with zero and +1...

Re: ramping with sextupoles
Dear Michael, Many thanks for your reply. I calculated the ramp for 1% energy spread. Without sextupoles I lost 23.4% of particles.Then I applied chromaticity correction to zero and I repeated the calculation. However I lost the same particles again. I was wondering if you can take a look to my file...

Re: ramping with sextupoles
Dear Michael,
Many thanks for your reply.
May I ask you about order in definition of dipole? If I use order =1 for dipole with and without sextupole I don't lose particles. In which case are we using order =2?
Best regards,
Samira

Re: ramping with sextupoles
Dear Michael,
Many thanks for your reply. It works now.
If I wanted to take in to account the effect of eddy current during energy ramping, Is Elegant able to calculate the effect? If yes, how and If you can refer me to an example it is great.
Many thanks in advance,
Samira

ramping with sextupoles
Dear Michael, I am using ramping example for my lattice. I wanna to consider the effect of sextupoles to correct the chromaticity. Without sextupoles the particles dont lose while with sextupoles, 70% of the particles lost. I used KSEXT for sextuploes. Could you please take a look at my files? Many ...

SDDS_InitializeInput
Dear Michael,
I tried to plot momentum aperture however I got the error of SDDS_InitializeInput. How can I solve this error?
Many thanks in advance,

Re: Ramping
Dear Michael, I would like to calculate the eddy current effects by energy ramping in a booster. Can you give me some hints or if you have some examples to share with me it would be wonderful. Many thanks in advance, Samira Ray, Using your files, I made a nicely-packaged example that can be run with...
