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 ...

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,
Samira

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...

Dear Michael,

Please find the attached.

Dear Michael,

Now it is working. However when I add some skew quads in my lattice I got the same vertical beam size. What is wrong in your opinion?

Many thanks and best regards,

Hello Michael,

I tried to calculate beam size for my ring but variation of the beam size is not small along the ring. Could you please take a look to my files?

Thanks alot and best regards,

Dear Michael,

I wanted to calculate touschek lifetime in the presence of an Id in my ring. While I wanted to calculate momentum aperture I got an error.
Error: No survivor found for initial scan for W0 #1 at s=0.000000e+00m

can you take a look to my files?

Many thanks in advance,

Dear Michael,

I had a basic question.
Concerning frequency map analysis, when do we introduce these parameters: delta_min, delta_max and ndelta?

Many thanks for your reply,
Samira

Dear Michael, Many thanks for reply. I have three questions. I do appreciate if you answer me. Why did you choose line distribution for the beam ? If I set center_on_orbit to zero I don't see any difference in the results. I am going to plot x-y space also, How can I do it? Many thanks and best rega...

Here are my files.
I forgot to add them.
