A key part of the high-energy physics research
portfolio involves plasma-based accelerator concepts, which include various
ionization processes. Because
accurate models of ionization physics are needed for the simulation of such
processes, this project will develop a comprehensive software library of
ionization models for a variety of relevant species.
Field-induced processes of tunneling, barrier suppression, and
multiphoton ionization will be included, as will electron-impact ionization. Together
with particle-in-cell codes, the library will be used to model plasma-based
accelerator experiments. Phase
I laid the groundwork for a prototype library to be completed in Phase II.
Software interfaces and prototype C code were developed to facilitate the
direct use of the ionization library from plasma simulation codes written in any
programming language. Tunneling
ionization models for H, He, Li, Csc and Rb were implemented and tested.
Lastly, the Li and Cs models were used for particle-in-cell simulations
of a new beam-driven plasma accelerator experiment.
A fully functional prototype of the software library will be implemented
in Phase II. A prototype web portal
will be developed to make parallel computing, data post-processing, and
automated visualization accessible.
Commercial
Applications and Other Benefits as described by awardee:
The technology should allow complex codes to become available to
collaborators in a controlled fashion. Customization
of the portal software to work with other scientific codes would be a potential
commercial service.
