“…As for DPSSL, an excimer-based fusion reactor is highly modular and single beamlines could provide up to 50 kJ of laser light [17]. Again, the thermal yield and the efficiencies requested for a viable commercial power plant [18] represent major technological challenges. The laser operates at 248 nm but a certain degree of tunability is offered by the fact that the same system design can be re-used for other gas mixtures [19] (e.g.…”

The existence of efficient ion acceleration regimes in collective laser-plasma interactions opens up the possibility to develop high-energy physics facilities in conjunction with projects for inertial confinement nuclear fusion (ICF) and neutron spallation sources. In this paper, we show that the pulse compression requests to make operative these acceleration mechanisms do not fall in contradiction with current technologies for high repetition rate ICF drivers. In particular, we discuss explicitly a solution that exploits optical parametric chirped pulse amplification and the intrinsic modularity of the lasers aimed at ICF.

“…The derivatives are related to the Sellmeier's equations for KDP since (18) so that the signal/idler angle Ω can be explicitly computed. These derivatives correspond to the group index for signal (n gs = cdk s /dω s ) and idler (n gs = cdk i /dω i ).…”

“…Investigations of both laser physics and laser-plasma interaction performed with single-shot KrF facilities AURORA (LANL, USA) [1], NIKE (NRL, USA) [2], SPRITE (RAL, UK) [3], ASHURA (AIS&T, Japan) [4], HEAVEN-I (CIAE, China) [5], and GARPUN (LPI, Russia) [6] and especially with rep-rate ELECTRA laser (NRL, USA) [7] have proved that e-beam-pumped KrF laser might be the best challenge for the direct-drive Inertial Fusion Energy (IFE) [8]. Fusion Test Facility (FTF) [9] with twenty angular-multiplexed 28-kJ amplifiers operating uninterruptedly at 5 Hz for two years (≥3·10 8 shots) with efficiency ≥ 6% is the next milestone on the path to KrF IFE.…”

“…The explosion is assumed to occur in a graphite dry-wall target chamber filled with xenon gas, as designed in the SOMBRERO study. 1 The target chamber gas can be designed to stop enough of the target x rays and ions and reradiate the energy over a long enough time that the graphite does not sublime. Computer calculations show how sensitive the design is to details in the target output.…”

Inertial fusion energy target output and chamber response: Calculations and experiments

et al. 2002

The emission of photons and energetic ions by the burn and subsequent explosion of inertial fusion energy ͑IFE͒ targets poses a threat to the survival of the target chambers in future IFE power plants. Immediately after the deposition of target output, the chamber can experience sufficient heating to cause vaporization, melting, and shock loading on chamber walls. Until high-yield targets can be ignited in laboratory experiments, predictions of the nature of the target output and the response of the target chamber must be made with radiation-hydrodynamics computer codes that need to be validated with relevant smaller scale experiments. Physical models of equation of state, opacity, and radiation transport are in special need of validation. Issues of target output and chamber response requiring experiments and computer modeling are discussed and initial results from experiments are presented. Calculations of x ray and debris output from direct-drive IFE targets are shown and sensitivity of the output spectra and chamber response to details of the physics models are discussed.
