Dear Michael, I tried using elegant 2021.4 and it worked. Thank you very much. And there is one more small suggestion about this command: There are some elements of zero length in my lattice file. By default, this command tracks particles at all elements, which results in some locations being tracke...

Hi Michael,
Thank you very much. I'll try another version.

Dear Michael,
I used the same example, and the files were uploaded as run1.zip.
I changed the theta_min as 0.00000000000013, still no particles can survive.
The version of elegant is 2023.4.
Here is the output of code displayed on the screen.

Best regards,

Hello Michael: Thank you very much for your explanation. I tried the elastic_scattering command in elegant, but encountered a new problem. It seems that all the particles are lost, even though they are within the DA found by find_aperture command. I tried different ranges for theta, but regardless o...

Hello Michael: I'm currently learning to use elasticScatteringLifetime, and I have a few questions about its parameters. usage: elasticScatteringLifetime -aperture <daFile> -name <string>(10Percentile) -twiss <twissFile> -output <filename> [-sPeriodic <value>27.61] [-pressure nTorr(2)] {-gasMix {APS...

And the other lines don't have this warning. I want to know what happened in those lines and whether i...
