•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.

Determine the optimal detector(s) for performing experiments with either an electron accelerator or a radioactive source.

MIT WORK PLAN FOR YEAR 1

16

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

17

(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.

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.

UCSD WORK PLAN YEAR 1

18

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 D 2.

•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.

19

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

20

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?

21

• Coordinators need to be appointed in the main research thrust areas

• Research Thrust and coordinators (* are responsible for coordination and reporting on progress)

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. Proposea candidate to serve on the executive committee.

23

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 Program committee: Meyerofer (Chair), Key, Ditmire Recruiting committee: Ren (Chair), Beg, Petrasso

24

INTERACTION

• Monthly conference calls (the CMSO has weekly cc!)

• The coordinators will report on the monthly progress:

Reports on: Laser-plasma interaction (Mori) Electron Transport (Petrasso) Fuel Assembly (Meyerhofer) HEDP (Beg) Theory/Simulation (Ren) Experiments (Key)

• Two annual meetings (Workshop and FSC meeting)

25

WORK PLANS and DELIVERABLES

• The work plans should include 1 and 2 year deliverables

• The coordinators should agree on the deliverables

• The coordinators should agree on the work plans

• The deliverables and work plans can be presented by the coordinators at the October conference call and reviewed by the Executive Committee

• A Center Work Plan will be developed by the Executive Committee based on the institutional work plans and the deliverables

CONCLUSIONS

• This meeting goals are:

(1) Review the work plans (2) Appoint coordinators (3) Appoint Summer School Committees (4) Develop a strategy to define deliverables (5) Develop a strategy to establish coordination and integration (6) Discuss the outstanding scientific issues (7) Develop a strategy to connect the Center activities to the broader HEDP community
