Collisional dissipation is expected to be the primary damping mechanism for helicon waves in low-temperature, high-density, moderate magnetic field plasmas. Combining a normal-mode analysis with high-resolution magnetic field measurements, we validate this expectation across a broad parameter space.…

In this paper, we address the problem of wave propagation within an unbounded time-modulated magnetized plasma in a Faraday configuration. We present an analysis formulated by coupling Maxwell's equations with the hydrodynamic evolution equation for the plasma current density, and casting the result…

In plasmas, a Langmuir wave is a bridge connecting external sources with waves or particles, whose properties are mainly determined by the shape, amplitude, dispersion relation, or phase of the Langmuir wave. Here we propose a scheme to generate coherent Langmuir wave trains with width as short as s…

The dissipation mechanisms in weakly collisional turbulent plasmas have been a longstanding topic of investigation. In recent years, one significant and promising development has been the use of the “scale-filtered” Vlasov-Maxwell equations to fully quantify the scale-by-scale energy balance, a feat…

In a series of magnetized-liner-inertial-fusion experiments performed at the Z pulsed power facility of Sandia National Laboratories, beryllium liners filled with deuterium gas densities between 0.7 to 1.4 mg/cc and a tracer amount of krypton were imploded. At the collapse of the cylindrical implosi…

Radiofrequency-heated, high-β, magnetized hydrogen plasmas in the Princeton field-reversed-configuration-2 device, with its magnetic-field-parallel radial boundary formed by eight discrete room-temperature coaxial copper rings, display constant density for times exceeding 150 ms. When the copper rin…

We present an experimental investigation demonstrating that the suppression of parametric instabilities in laser-plasma interactions under conditions relevant to direct-drive inertial confinement fusion, specifically backward stimulated Raman scattering (SRS) and two-plasmon decay (TPD), shows the e…

The aim of this work is to predict the opacity of plasmas under stellar conditions. We focus on iron and nickel, as these elements have been extensively investigated both theoretically and experimentally. In certain regimes, notably under nonlocal thermodynamic equilibrium, calculating the spectral …

Progress towards achieving net gain from nuclear fusion is typically characterized by the triple product nTτ. Although stellarators have several benefits for a reactor, such as the inherent steady-state capability and the lack of disruptions, the maximum achieved triple product has historically lagg…

Three-dimensional (3D) asymmetries and their associated residual kinetic energy (RKE) are a major performance-degradation mechanism in inertial-confinement fusion (ICF) implosions at the National Ignition Facility (NIF). These asymmetries can be diagnosed with the three neutron imaging systems field…

How momentum, energy, and magnetic fields are transported in the presence of macroscopic gradients is a fundamental question in plasma physics. Answering this question is especially challenging for weakly collisional, magnetized plasmas, where macroscopic gradients influence the plasma's microphysic…

Hydrodynamic instabilities seeded by isolated internal defects remain a critical performance-limiting factor in inertial confinement fusion experiments. Here we extend the concept of dynamic stabilization via temporally modulated laser pulses from the main drive [K. G. Zhao et al., Phys. Rev. E 109,…
