Re: Lost particles during tracking

Dear all, I have more or less the same problem as our colleague Ian. I put the dimensions of my vacuum chamber to compute the DA using MAXAMP element (see the lattice file attached) and the particles become lost at 12 mm. VCHAMBER: MAXAMP,X_MAX=0.035,Y_MAX=0.0125 MHU640: MAXAMP,X_MAX=0.028,Y_MAX=0.0...

Chromaticity correction with multipole errors

Hi all, I want to introduce the multipole errors in my lattice to check the effect of these errors in the calculation of dynamic and momentum acceptance. I have created the input sdds files and I have introduced the systematic errors in the quadrupoles and sextupoles definitions in the lattice. But ...

plot the vacum chamber

Hi all,

Do you know how to plot the vacuum chamber with elegant (horizontal aperture vs distance along the ring)? Do you have some example?

Thank you in advance.
Have a nice day

Documentation of the algorithm

Hi, I am trying to understand in detail how is implemented the MOGA's algorithm in the geneticOptimizer script. In fact, I am interested to understand the processes called selection, evolution and crossover. Can you send some documentation that explains in detail this concepts used in APS ? Thanks X...

Re: APSStrictParseArguments

Hi, Finally we resolved the problem: We saw that some of the oag package were installed in /usr/lib and /usr/bin. Then, we reinstalled it in the path /usr/local/ of our cluster. The second step was export the PATH in ~/.bashrc : export PATH=$PATH:/usr/local/applications/elegant:/usr/local/applicatio...

Change the optimizer's path of a new directory

Hi there! I ran the optimizer in the directory /home of my cluster with good results. Now I want to run it in another directory (/lnec) because /home has a limited memory. I copied exactly the same /home's files in the new directory and I tried to run the optimization in this new directory. But I ha...

APSStrictParseArguments

Hey there, I am experiencing some trouble while testing the mogaRing examples. Specifically, at step 3 of the GuideToUse geneticOptimizer -input optim1.sdds -reduce 1 reports in a file called "o" (I imagine that's a product of changing -j for -eo, see below): invalid command name "APSStrictParseArgu...
