The OPAL Discussion Forum

["Adelmann Andreas (PSI)" <andreas.adelmann AT psi.ch>]

Hello Dragos, beam loading can not be modelled with the current version of OPAL.

However in https://journals.aps.org/prab/abstract/10.1103/PhysRevAccelBeams.20.052002

an interesting method was published which could be implemented without bigger problems in OPAL.

This could be an interesting project if you want to be involved with the OPAL development. 

Cheers A

Dear All,
I am modeling an emitted beam being accelerated by a few RF cavities. The beam
emission time is longer than the RF period. I expect to see that final beam
energy has some dependence on the beam current but it does not. How can I
correctly model the beam loading in OPAL?

Thanks,
Dragos
