We introduce a simple symmetric Hamiltonian map that models the magnetic field lines of a double-null diverted tokamak and compare its behavior with the corresponding symmetric single-null map. The phase-space structure of both models is characterized using the finite-time Lyapunov exponent and the …

Based on the data recorded during the Parker Solar Probe mission, it can be suggested that there is no balance between kinetic and magnetic energy in the vicinity of the Sun. The spectra collected at different radial distances show an energy transfer from one component to another, followed by a chan…

A wide variety of spectroscopic methods are used for the diagnostics of laser-produced plasma. One particularly powerful diagnostic is high-resolution emission line spectroscopy, in conjunction with atomic calculations and radiation hydrodynamic simulations. In this work, we present line-resolved sp…

In indirect-drive inertial confinement fusion (ICF), a hohlraum serves the purpose of converting laser energy into thermal x-ray energy. This process involves the interaction of low-density ablated plasmas, which can give rise to weakly collisional shocks characterized by the Knudsen number Kn on th…

Physical models aimed to reproduce basic features of the solar sunspot cycle are typically based on the solar dynamo mechanism. Usually qualitative arguments are used to define parameters of the model, among which a challenging component is the nonlinear form of quenching of the α effect governing r…

Plasma discharge devices have recently emerged as compact and versatile tools for particle beam manipulation. Building upon the active plasma lens (APL) and its curved extension, the active plasma bending, this work introduces the concept of the plasma discharge undulator (PDU). In a PDU, a high-cur…

The fast ion (FI) on turbulent transport is one of the key topics of magnetic confinement fusion. This work focus on the impact of FI pressure gradients on turbulence in a high-β plasma scenario using gyrokinetic simulations. Linear analyses reveal that FIs strongly stabilize ion temperature gradien…

We present a method for generating a narrowband terahertz (THz) emission using a radially oscillating plasma oscillator formed in a plasma slab with a longitudinal paraboliclike density profile. Through quasi-three-dimensional particle-in-cell simulations, we observe more stable, longer-lived plasma…

Plasma disruption in tokamaks is one of the most serious challenges in fusion research. Recent studies suggest that microturbulence may play an important role in facilitating thermal quench (TQ) and resultant disruptions, but experimental evidence on the impact of turbulence on the dynamic evolution…

Recent stellarator reactor designs demonstrate mostly outward turbulent particle transport, which, without advanced fueling technology, inhibits the formation of density gradients needed for confinement. We introduce “SQuID-τ,” a self-fueling quasi-isodynamic stellarator capable of sustaining densit…

The laser direct-drive fast ignition scheme is a candidate for inertial fusion energy reactors. The scheme promises higher fusion gains (fusion energy divided by laser energy) than with conventional central hot-spot ignition. For a particle beam (electrons or ions) to reach and heat the compressed f…
