Dear Didier, I would like to know if TraceWin has a way to check the effect of multipoles. I plot the Gradient in the window charts, but the plots are the same with and without multipoles. In addition, I have a doubt, when I defined a GFR no null, the multipole coefficient that give is the relative ...

Dear All,

When I plot the emittance parameters of the phase-space distributions. Two different values of the rms emittance are printed.
Please see the red marks on the attached figure.
Best regards,

Bruce

Dear Didier,

Thanks for the reference. I will be working on it.

Best regards,

Bruce

Dear Didier,

Thank you very much for your advices.

Could be possible to have access to the "static" variable script that you used to keep in memory the diagnostic values?

Thanks for your help,

Bruce

Dear Didier, Thanks for your reply, and sorry to be ambiguous with my question. As you kindly explain in your answer, if you have the same type of element in 3 positions, you can relate by the following criteria. Vcr= (diag(n-2)-diag(n-1))^2 + (diag(n-1)-diag(n))^2. How do you access the nth diag va...

Dear Didier, The DIAG_DSIZE2 (similar to DIAG_DSIZE3 and DIAG_DPSIZE2) associates delta size in X and Y at two different points of the lattice. Could you explain me or sent the script of how it is done? I want to use something similar to associate some beam properties at different point in the latti...

Dear Didier,

Thanks for your help.

I installed the new version of TraceWin and I did not see the error again. I will continue with the test.
I will let you know if I see the error again.

Best regards,

Bruce

Dear Didier, Thanks for your comments. I downloaded a check again the files. This is a screenshot of the project. Run.png According to my understanding, from the element 3 to 5 is the 1st dipole (Edge+Bend+Edge) and from 16 to 18 the 2nd dipole. (See the red marks) No cavity is defined. Similar the ...

Dear Didier, I sent you a simplified version of lattice where the error occurred. BTL_TEST.zip I have to say that the error is intermittent (i.e., sometimes occurs and sometimes no). Thus, I included the output (most of them) for a case where the error appeared. Thanks for your help and support. Bruce

Dear Didier, I noticed when I applied error gradients in the bending magnets, something strange happened. This is how I applied the error. ERROR_BEND_NCPL_STAT 2 1 0.0 0.0 0. 0. 0. 0.8 EDGE 22.5 4500 250 0.45 2.8 250 1 BEND -45 4500 0 250 1 EDGE 22.5 4500 250 0.45 2.8 250 1 This is the error data fi...
