An extended hydrodynamics model for inertial confinement fusion hohlraums

Autor: Larroche, Olivier

Publikováno v: Eur. Phys. J. D 75:297 (2021)

In some inertial confinement fusion hohlraum designs, the inside plasma is not sufficiently collisional to be satisfactorily described by the Euler equations implemented in hydrodynamic simulation codes, particularly in converging regions of the expa

Fokker Planck kinetic modeling of suprathermal alpha-particles in a fusion plasma

Autor: Peigney, Benjamin-Edouard, Larroche, Olivier, Tikhonchuk, Vladimir

We present an ion kinetic model describing the ignition and burn of the deuterium-tritium fuel of inertial fusion targets. The analysis of the underlying physical model enables us to develop efficient numerical methods to simulate the creation, trans

We investigate the coherence of plasma-based soft X-ray laser (XRL) for different conditions that can alter the electron density in the gain region. We first measure the source temporal coherence in amplified spontaneous emission (ASE) mode. We devel

Development of efficient soft x-ray laser plasma amplifiers adapted to seeded operation, requires a better control over amplifier transverse spatial extent, brilliance control and gain lifetime. Here it is shown that pumping the plasma amplifier with
