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.
