Re: Multi-objective direct optimization of DA and MA

Monika,

I don't see anything obviously wrong with the processed file. Can you upload the input file you are using with geneticOptimizer?

Re: rf_setup is broken in 2025.1

Mikhail,

This bug was introduced when I refined the calculation of radiation integrals to better include orbit effects. The fix was pretty simple, see attached.

Thanks for the bug report.

Re: rf_setup is broken in 2025.1

Mikhail,

The problem is caused by dipole magnet called R.MB12, which has ANGLE=0. I'm not sure why it is a problem now and not in the previous version, but I'll find a solution now that I can see it.

Mikhail,

I'm not able to confirm this problem on linux or windows. Can you upload files that cause the problem?

Thanks--Michael

Re: Multi-objective direct optimization of DA and MA

Monika, I don't understand why it isn't submitting more jobs. Can you verify that you have a set of files with extension .proc? Also, can you upload the input file you use with geneticOptimizer? I'm looking for the MOGA example files. They used to be on our web page but I don't see them now. --Michael

Re: Calculation of Sliced Beam Parameters

Tiansk, When performing slice-based IBS, elegant calculates an equivalent rms bunch length that can be inserted into the IBS growth rate equations, which are expressed in terms of the rms bunch length. The IBS rate is proportional to the integral of the longitudinal particle density rho(s) squared (...

Re: Multi-objective direct optimization of DA and MA

You should see several additional files created by the geneticOptimizer script with names matching optim1.*. In particular, look for optim1.sort, which will have summary data for all runs that has been sorted. There will be a column Rank that gives the ranks from the non-dominated sort. The geneticO...

Re: Ring Injection/Extraction centroid/floor coordinates calculation

Nick, For injection modeling, what I typically do is to model the septum as a bending magnet, taking it to be the last element in the transport line. I then have a MALIGN element that offsets the beam centroids to put things into the ring coordinate system. This allows tracking the injected beam wit...
