Each advisor will receive a questionnaire
to provide input to the FSC
The input of the advisor will be used to keep
the FSC productive and competitive through
the next funding cycle.
The purpose of this meeting is to present and
discuss the latest results as well as to coordinate
a work plan for the next two years
FSC
The FSC has a strong simulation program
in place (UR,UCLA,UNR). Can we include LLNL?
The FSC is currently conducting 3 signature
experiments
The FSC is also sponsoring several collaborative
experiments with LLE, NLUF, RAL, LLNL
Two task forces have been charged with exploring
the possibilities for additional signature experiments
One task force has been charged with conducting
PIC and Hybrid code benchmarking

Code development: Quadratic spline current
deposition and field interpolation allows
higher density simulations with OSIRIS

Code development: a binary collision model
has been implemented in PICLS. It allows to
simulate fast electron stopping in dense plasmas
FSC
E-stopping power from PICLS compared to NIST database
(Sentoku)
Code development: the LSP collision model is
extended to the relativistic regime. It allows to
perform realistic FI integrated hybrid simulations
in ultra dense plasmas.

Osiris have been benchmarked on the Weibel
instability and e-beam wake excitation
