Re: Compare the result of the frequency map with AT

Dear Michael Borland I confirm your file. It has expected result. But your input file has two difference. My input file has "maxamp" for 6mm undulator gap and don't define the ymin. I attached it. I think the maxamp could be make difference. Now, I check it. Have a nice day and weekend. From Hwang J...

Re: Compare the result of the frequency map with AT

Dear Michael Borland Thank you for giving tips. So, I test your tips. But the second one is not so good. Because the frequency map depend on the x_min. This result is attached. The file name is "check". I simulated the fma with 20 insertion devices. But This result is very strange. The center of the...

Re: Micro-bunching particle tracking

Dear Michael Borland

Thanks for your reply. I agree with your opinion.
So, I attached the "PFILTER" element at the upstream of the linac.
But The bunch distribution at the end of linac has still long tail. So, I will test many things.

Have a nice day.

Micro-bunching particle tracking

Dear Borland and every-body. :) Hello. I simulate the linac tracking using real beam distribution. This beam distribution get from injector simulation using parmela. The bunch was micro-bunched by buncher cavities. This figure is attached. It has 10% energy deviation with ~125 MeV. General case, the...

Re: Compare the result of the frequency map with AT

Dear Borland Thank you for kindness your reply. These result has some purple color at the center of horizontal plane. Maybe the purple color means the particle has very large tune shuft. I think it is come from 3rd resonance line. Is it corrected? and Is it fine to operation? I want to know your opi...

Compare the result of the frequency map with AT

Dear every one and Borland Sorry for bother you. Thesedays I simulate the frequency map in PLS-II. But result of elegant is diifferent with AT. So, I want to know the reason of the difference. I attached the file of the result of elegant and AT. Which thing make the difference? :) If someone know th...

Dynamic aperture with multipole error of dipole.

Dear Michael Borland and every one. Hello. I have a one questions. I want to simulate the dynamic aperture with multipole errors of magnet. I already know to contain the multipole error in quad and sextupole magnet. But, The dipole manget don't know. Could explain to me? Have a nice days. Sincerely ...

Re: Can elegant perform dynamic Aperture optimization ?

Hello, Dear all. I'm also interested in optimization of dynamic aperture. I trying to run the example. But It is not operate in windows OS.[It is desktop, Win7] This problem is samely occur in my linux PC.[It is desktop, Ubuntu9] I get some error message, such as "couldn't execute "csub": no such fi...

Re: frequency map analysis

Dear Michael Borland

Hello, Sorry to late reply. I attached the lattice file for FMA.
I simualte FMA under 1000 particle and 2000 turns.
Sincerely yours.
