Researchers achieved high areal densities in plasma cores using low-adiabat implosions on the OMEGA laser. These results are optimal for fast ignition inertial confinement fusion energy research.

Area of Science:

  • * Physics
  • * Plasma Physics
  • * Inertial Confinement Fusion

Background:

  • * Achieving high areal density (rhoR) is crucial for efficient fusion energy gain.
  • * Fast ignition requires specific plasma conditions, including high rhoR, to effectively couple the ignitor energy to the fuel.

Purpose of the Study:

  • * To investigate the generation of massive plasma cores with high areal densities.
  • * To assess the suitability of these conditions for fast ignition inertial confinement fusion.

Main Methods:

  • * Implosion of thick plastic shells (40 microm) filled with D2 or D3He fuel.
  • * Utilizing low-adiabat (alpha ~ 1.3) and low-implosion velocity (~2 x 10^7 cm/s) conditions on the OMEGA laser.
  • * Driving targets with 20-kJ relaxation adiabat-shaping laser pulses.

Main Results:

  • * Measured burn-averaged areal densities of 0.130+/-0.017 g/cm2.
  • * Achieved peak rhoR during burn of approximately 0.24+/-0.018 g/cm2, the highest recorded on OMEGA.
  • * Proton spectra kinetic energy downshift agreed with theoretical predictions.

Conclusions:

  • * The achieved areal densities are optimal for fast ignition scenarios.
  • * Simulations predict empty shells could reach 1.3 g/cm2 (2rhoR), sufficient for stopping fast ignitor electrons up to 4.5 MeV.
