Workshop Working Groups    

Computational Accelerator Physics
Group-Leader: John R. Cary, U. Colorado and Tech-X Corp. (cary@colorado.edu)
Co-Group-Leader: David P. Grote, Lawrence Berkeley Lab. (DPGrote@lbl.gov)

Theme: Discuss and analyze computational tools that will calculate fast non-linear problems in such accelerators as above.

The WG will put forward a plan for benchmarking codes of the same type with against each other, and well as codes of different types against each other to the extent possible. The WG should also propose or identify new, faster algorithms that can provide accurate models for accelerators or aspects of same and be useful for parametric studies and the design of new accelerator concepts.

Computation has become an increasingly important tool in the development, analysis, and diagnosis of advanced accelerator concepts and experiments. The goal of this working group is to identify the state of the art of advanced accelerator computation to determine the needs for new software and hardware capabilities for advanced accelerator concepts. This includes applications of computation to the LWFA and PWFA concepts, MM wave sources and advanced EM structures, and exotic acceleration schemes, along with faithful representation of the appropriate physics, including wakefield formation, injection, dynamics, and ionization in plasma acceleration schemes, laser-solid interactions in exotic acceleration schemes, and microwave breakdown for MM wave sources and advanced structures.

We will begin with discussions of the status of this field through talks by major code developers on (1) state of the art simulations, (2) code capabilities (physics, algorithms, visualization), and (3) availability (through collaboration, downloadable, module at NERSC, ...) Our next set of discussions will include participants from other working groups, who will describe the state of the modeling of one or more of their concepts, with special emphasis on unmet needs. The working group will then discuss how to provide those unmet needs, perhaps in smaller groups. Such discussions will determine whether existing codes can meet those needs. If not, discussions will determine what will have to be added to existing codes (physics, algorithms, ...) to meet the modeling needs of other concepts. In any case, the working group will develop an assessment of whether existing hardware will be able to carry out the proposed modeling.
