The OPAL Discussion Forum

["Snuverink Jochem (PSI)" <jochem.snuverink AT psi.ch>]

Dear Huiwen,

Concerning questions about OPAL, it is best to use the email list as more users and members of the developer's team will see your message, and you'll get a quicker response.

1) @Matthias, can you answer that question perhaps?

2) I agree there is no reference in the Manual to the h5part format. That should be added and thanks for pointing that out. There is some information here: https://gitlab.psi.ch/H5hut/src/wikis/home

@Achim, can you point Huiwen to how he can convert his ASCII field map to a h5part file?

Best regards,

Jochem

Dear Jochem Snuverink,

Hi. I have previously sent email to inquire about OPAL input for B fieldmap. Currently I managed to simulate the single particle tracking using opal-cycl. However, when I move onto deeper calculations, such as bunch calculation and central region calculations, I face some troubles. I did send inquiries to some of the members in the mailing lists directly but I receive no reply. Thus, I would like to ask for help again here. I sincerely appreciate if anyone could help in clearing my confusion. 

1) In manual 2.1, the coordinate system of .stat output in opal-t is given. From my interpretation, the local frame in .stat file is similar to that defined in opal-cycl. However, when I changed sigmax in distribution input of type=GAUSS, both RMSx and RMSy changed. The RMSx and RMSy in .stat file seems not to be consistent with the X and Y defined in local frame of opal-cycl. So, in that case, I would like to know the definition of RMSx and RMSy given in the .stat file. 

2) I would like to use an eletric field map in OPAL for central region calculations. However, in type=BANDRF, the input format for rfmap is in .h5part. Regarding this, I would like to ask if you had any reference format of .h5part file so that I can translate my ascii field map to H5part?

Thank you very much for your help.

I am looking forward to your soon reply.

Best regards,

Huiwen
