Re: run_setup very slow for very long beam line.

Hi, Michael

I recompiled elegant and the improvement is drastic. Thanks again.

However I failed in compiling Pelegant, with error on missing libSDDSmpi. Do I need any change when I compile SDDS for mpi version?

Best,
Yue

Re: run_setup very slow for very long beam line.

By the way, I am using the macos binary, version 26.0.2.

Re: run_setup very slow for very long beam line.

It would be great if you can take a look. Please find the lattice file in attachment. Also the run_setup is : &run_setup lattice = test.lte, p_central = 12958.9317133, rootname = 1KPartRAD_MLIGN_1um_CENTER, centroid = %s.cen, sigma = %s.sig, use_beamline = start_to_end, &end Thanks a lot. Yue

Re: close orbit for large momentum offset

Hi, Michael Thank you for your reply. Yes, it is slightly different. But as you said the twiss_output cannot handle large momentum deviation. I created 8 particles (4 for x-xp phase space, 4 for y-yp) around the closed orbit using SDDS_BEAM, and deduct the map from the tracking result. In this way I...

run_setup very slow for very long beam line.

Hi, Michael I generated a quite long lattice and the run_setup takes 8 minutes to finish. Below are the output of run_setup: Seeding random number generators length of beamline START_TO_END per pass: 9.175199952533640e+04 m statistics: ET: 00:07:57 CP: 476.88 BIO:0 DIO:0 PF:0 MEM:0 Is that normal to...

Re: close orbit for large momentum offset

Hi Michael, Thanks a lot for your prompt answer, especially this late. It is very strange that I get exact same answer with /without the closed_orbit command before twiss_output command. Did I do anything wrong? elegant file 1 (no close orbit): ÷_elements divisions = 100, type = CSBEND, name =...

Re: close orbit for large momentum offset

HI, Michael However, this deviate from the calculation from other codes. We use several codes to benchmark with each other. Madx and elegant cannot give the right result. (MADX_PTC can give the correct result) We narrowed down the reason, and guess that elegant 's result does not consider the closed...

Re: close orbit for large momentum offset

Hi, Michael Please see the lte and ele file below, since they are short: test.lte cal_cell.ele Since the delta is large, the closed_orbit is ~5mm deviated from the reference orbit. I expect the optics with respective to the reference orbit and the closed_orbit be quite different. However, I set the ...

Re: close orbit for large momentum offset

Hi Michael, I returned to this topic after a year :). I managed to calculated the closed orbit correctly. How do I calculate the twiss parameters with respect to the calculated closed orbit? I used the sequence followed your recommendation: &run_setup &closed_orbit &twiss_output # it seems the the f...
