Dear Users,
1. Below is a very rough description of the CSR Class library to be installed in the next version. The actual usage may be shown later.
Class CSR:
- calculation of CSR electric field and longitudinal wake function for a beam pipe with an arbitrary cross section and bending radius. The cross section must be uniform along the orbit, but the bending radius can be changed.
- mainly for the longitudinal field so far, but transverse components has been already calculated anyway in the functions, so application on transverse effects will be not very difficult.
- read external wakes and convert to the CSR format file.
- parallel processing.
- some GUI functions.
Class CSRStability:
- examine longitudinal beam stability with impedances including CSR, by multiparticle tracking and also "Oide-Yokoya" method.
- tracking can start from the Haissinski solution.
- automatic scan through bunch intensity.
- parallel processing.
- some GUI functions, including generation of a movie of the particle distribution in the phase space.
