| Research Abstract |
Numerical Codes for particle accelerator wake field analysis which are based on time domain boundary element method (TDBEM) are developed.
The TDBEM gives us attractive possibility of self-consistent analysis of wake fields and charged particle motion in the next generation high energy particle accelerators, especially for analysis of coherent synchrotron radiation in bunch compressor section of the Linear Colliders.
During the term of this project, the TDBEM codes were developed for axi-symmetric 2D,3D and 2.5D accelerator cavity systems. Then the biggest problem of TDBEM in practical use was requirement of big RAM capacity. For this, MPI parallel computation system was constructed and the TDBEM codes were turned to the MPI parallel computation.
It was confirmed that the wake potential simulation showed us very good agreement with conventional FDTD analysis for all of axi-symmetric 2D,3D and 2.5D TDBEM codes. And scalability in MPI parallel computation also gave us very good performance. And then, at the same time, particle trajectory simulation codes were also included in the codes to do self-consistent analysis of the wake fields and particles dynamics.
It will be future works to apply the TDBEM codes to analysis of particle dynamics in real bunch compressors.
