Transcript The proposed FSC provides an integrated program to study

OUTLINE
•What have we promised? Where are we now?
• The Center and HEDP
• The Work Plan by institution.
• FSC: COORDINATION
• FSC: INTERACTION
• FSC: EDUCATION

New experimental and simulation capabilities make
this an opportune time to create this Center
• The experimental opportunities in this field are unprecedented:
– The U.S. has three large high energy compression systems
(Z, OMEGA, and NIF).
– All of these systems are adding Petawatt laser capability.
– Unexplored states of matter can be created with this combination.
• Numerical simulation capability is advancing rapidly:
– State of the art 3D explicit PIC modeling can now describe the laser
plasma interaction and relativistic electron generation
– New hybrid PIC modeling is being developed to describe
the transport of relativistic electrons to the ignition spot
• Graduate students are attracted in growing numbers to the exciting
new science of short-pulse high energy-density physics.

The Center will coordinate the major research areas
associated with Fast Ignition
• This Center will integrate a currently dispersed effort throughout
the country and provides coordination among the major research areas:
– Numerical simulation of intense laser matter interactions and transport
(UCLA, UNR, LLNL, UR, MIT),
– Experimental investigation of intense laser matter interactions and
transport (OSU, UT, UNR, UCSD, LLNL, MIT, UR)
– Target Fabrication (GA, UR, LLNL)
– Fuel Assembly (GA, MIT, UR, LLNL)
– Integrated Experiments and Simulations (all participants)
– Diagnostic Development (OSU, UCSD, MIT, UT, LLNL, UR)
• Fast Ignition is not part of NNSA’s program plan. NNSA has no plans to
provide the resources required to create this type of collaborative activity.

HEDP Summer School confirmed for
Aug 7 through Aug 13 at UC Berkeley
•
The key person for the HEDP organization is Don Correll
•
Participant number at the workshop estimated at 50 with the
possibility being as high as 70.
•
Clark Kerr Campus is located six blocks southeast of the main UC
Berkeley campus and has its own parking.
•
Don needs a better estimate of the number of participants
•
The Granlibakken Hotel and Resort in Lake Tahoe (where
ICUIL is taking place: http://www.llnl.gov/icuil) can be an alternative.
• A committee needs to be assembled to help Don with the
Summer School organization ( advertising, program, lodging)

U. Rochester Work Plan for Year 1
•Development of hydrodynamic simulation capability to model
the implosion of spherical targets with embedded cones
•Development of hybrid code capability (LSP and models for
hydrodynamic codes) to model the generation and propagation of
high energy electron beams in the high density, compressed cores
of imploded cryogenic targets,
•Fuel assembly experiments with spherical plastic shells
with embedded gold cones.
•Development of diagnostics for integrated (PW plus
implosion) experiments planned to begin on
OMEGA/OMEGA EP in FY07.
14
MIT WORK PLAN FOR YEAR 1
• Validate experiments for testing electron scattering and energy
deposition in hydrogenic ice by extrapolating the experimental results to
plasmas.
• Model preheat from electron penetration in a range of ICF scenarios.
•Develop a Monte Carlo code for simulating the interactions of fast
electrons with dense hydrogenic plasmas.
•Perform simulations to aid in the design, and demonstrate relevance and
feasibility, of experiments for testing analytic and numeric models.
•Design experimental scenarios relevant for studying the transport of
electrons, in the energy range from about 0.05 MeV to 2 MeV, in
hydrogenic ice, in Be (Z=4), and in Al (Z=13).
•Determine the characteristics of a suitable electron accelerator and/or
radioactive source. Determine the optimal detector(s) for performing
experiments with either an electron accelerator or a radioactive source.
15
OSU WORK PLAN YEAR 1
(1)
Analyze data on penetration depth of photo-generated fast
electrons into normally dense matter obtained from
experiments at Rutherford Laboratories (RAL).
(2) Compare experimental results to LSP/Lasnex calculations
(3) Prepare experimental plan to diagnose electron transport in
isochorically heated targets on Omega/EP
16
UCSD WORK PLAN YEAR 1
(1) Study of interaction of short pulse high intensity laser with the critical
density surface including absorption, fast electron generation and
deposition of energy in targets of varying conductivities.
(2) The effect of target resistivity, return current and target shape
(e.g., layered cylinder) on angular distribution of the electron beam
will be extensively studied. Targets consisting of foam on the rear surface
and sandwiched between two thin foils will be used
for the return current studies. A detailed study of coherent and incoherent
optical transition radiation (OTR & ITR) from the rear surface of the
targets will be performed.
(3) Numerical simulations of the above-mentioned experimental conditions
will be performed using LSP code.
17
GA WORK PLAN YEAR 1
•Design and build the complex targets needed for the various
transport and implosion experiments. Develop targets suitable for
electron transport measurements in cryogenic D2.
•Produce the required targets and deliver them to the
experimental team in time for each campaign.
• A post-doc (5.73 person-months/year) will work with the rest of the
experimental team to carry out the experimental shots and analyze the
results.
18
UT, UNR and LLNL
• The FSC is supporting a graduate student at UT. No support is
currently requested by UNR and LLNL
• Additional support for UT, UNR and LLNL can become available
depending on their Work Plans and funding availability
within the center
• The participation of UT, UNR and LLNL greatly
enhances the FSC visibility and provide
possible access to the UT and UNR facilities
19
The FSC Work Plan must show COORDINATION
• For example: how the UCSD experimental plan differ from
the OSU plan? What are the difference in
the electron transport experiments proposed
by the two groups? Can those experiments be
coordinated to avoid redundancies?
• Almost everybody will be using LSP to benchmark the experiments.
Will one or two FSC members run LSP for everybody else?
Will each group develop a simulation capability with LSP?
It is probably more efficient to establish
an LSP user group within the Center that will run LSP for all
different experiments funded by the Center
• We have the PIC experts in the Center.
Shall we develop a new simulation tool? Maybe, a new hybrid code?
20
COORDINATION
• Coordinators need to be appointed in the main research thrust areas
• Research Thrust and coordinators (* are responsible for coordination
and reporting on progress)
Laser-Plasma Interaction
Fuel Assembly
HEDP
(Li-Petrasso*/Freeman)
(Meyerhofer/Stephens*)
(Beg*/Ditmire)
Cross-cutting areas
Theory/simulation
(Ren*/

(Key*,
Meyerhofer)

(Mori*/Cowan)
21
The Cross-Cutting coordinators are necessary for maintaining
a balanced activity, assessing the needs of the thrust areas,
and developing the most effective strategies
• Experiments: Are the proposed experiments advancing the
scientific understanding in an efficient and coordinated fashion?
Is the research balanced among the different areas?
• Theory/Simulation: Do we need an LSP group? Do we need to
develop a new simulation tool?
HEDP: the HEDP coordinators will develop
a strategy to involve the non-fusion HEDP
community in the Center activities. Propose
a candidate to serve on the executive committee.
22
A summer school organizing/program/recruiting committee
need to be assembled
•
A significant amount of work is required to organize the
HEDP summer school
•
Don Corell has already started negotiations with UC Berkeley
and will be the primary contact person for the summer school
•
After the lodging arrangements are completed, the program
and recruiting strategies need to be put in place
•
We need an organizing committee to assist Don,
a program committee to and a recruiting committee
Organizing committee: Correll (Chair), Mori, Betti
