Tnsa enhancement for energy increase beyond present day record of 67 mev

Obvious route: « brute force »

(laser energy increase)

TNSA enhancement for energy increase: beyond present-day record of 67 MeV?

  • 2: Use of low-density plasmas

  • 3: Geometrical e- confinement

  • 4: Tightest laser focusing

  • More clever strategies?

  • 1: Decrease the target thickness (less e- spread + volumetric target heating)

Eli np allows to explore wdm regimes currently unreached

ELI-NP allows to explore WDM regimes currently unreached

Higher efficiency proton beams will allow reaching unexplored hotter plasma zones (R P A: 60 % efficiency, compared to 4 % TNSA)

  • Understanding of transition phases and thermo-dynamical properties

  • Laboratory astrophysics (conditions only existing in stellar interiors)

50 eV

Stopping power

Equation of state


Eli np can be used also for experiments in the icf or related applications

ELI-NP can be used also for experiments in the ICF or related applications

  • Higher proton energy for probing thicker material

  • Higher laser energy for higher energy electrons

  • Tailoring of heating temperature

Higher intensity laser = brighter beams allows

measurement of hotter electron transport
