21. Data analysis and numerical modelling of laser-plasma instabilities in NIF shock ignition experiments

Alessandro Ruocco (STCF - RAL - CLF)

oral

The shock ignition approach (SI) [1] to inertial confinement fusion (ICF) [2] relaxes the ignition requirements by splitting the compression phase, led by a low-intensity laser pulse, from the ignition phase, driven by laser pulses of around 10$^{16}$ W/cm$^2$. Albeit more robust against hydrodynamics instabilities, SI is more vulnerable to laser-plasma instabilities (LPI) [3], which produce...

48. Direct Measurements of DT Fuel Preheat from Hot Electrons in Direct-Drive Inertial Confinement Fusion

Alison Christopherson (Lawrence Livermore National Laboratory)

Invited

In laser fusion, a spherical shell of a low-Z ablator (CH, HDC, Be or others) layered with cryogenic DT ice is accelerated inward on a low adiabat to achieve high fusion yields and areal densities with minimal driver energy. Hot electrons generated from laser--plasma instabilities can severely degrade the implosion performance by preheating the DT fuel, resulting in early decompression of the...

74. High-power laser interaction with additively manufactured micro-structured materials

Mattia Cipriani (ENEA - CR Frascati)

oral

The research on Inertial Confinement Fusion (ICF) is always requiring the development of new types of materials. The structure of the fusion capsule has to be precisely tailored to ensure an optimal performance for the implosion and ignition, and also a reliable reproducibility of the plasma behavior from shot to shot, in the view of a future fusion reactor. Among the various processes...

62. Impact of Laser Bandwidth on LPI in Conditions Relevant for Shock Ignition

Leonida Antonio GIZZI (CNR, Istituto Nazionale di Ottica, Pisa, Italy)

oral

With the recent outstanding progress towards Inertial Confinement Fusion (ICF) ignition at the National Ignition Facility, the interest for high gain Inertial Fusion Energy (IFE) is rapidly expanding. Shock ignition (SI) is based on direct drive and relies on a strong shock wave (>300 Mbar) to be launched by means of a short laser spike (300-500 ps) irradiation at intensities around 1016 W...
