  • What have we promised? Where are we now?

  • The Center and HEDP

  • The Work Plan by institution.




New experimental and simulation capabilities make this an opportune time to create this center l.jpg
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 l.jpg
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 andtransport(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.

U. Rochester Work Plan for Year 1 expertise

  • 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


Slide15 l.jpg


  • 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.

Slide16 l.jpg

OSU WORK PLAN YEAR 1 expertise

  • (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

Slide17 l.jpg


  • (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.

Slide18 l.jpg

GA WORK PLAN YEAR 1 expertise

  • 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.

Slide19 l.jpg

UT, UNR and LLNL expertise

  • 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

Slide20 l.jpg

The FSC Work Plan must show COORDINATION expertise

  • 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?

Slide21 l.jpg

Laser-Plasma Interaction expertise

Particle Transport

Fuel Assembly





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

  • Research Thrust and coordinators (* are responsible for coordination

  • and reporting on progress)









Cross-cutting areas

Slide22 l.jpg

The Cross-Cutting coordinators are necessary for maintaining expertise

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.

Slide23 l.jpg

A summer school organizing/program/recruiting committee expertise

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

  • 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
