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,…

Dust clusters with crystalline structure, formed by charged microparticles in complex plasmas, can undergo phase transitions under external influences. While many studies have focused on the effects of temperature and pressure on crystallization, it is worthwhile to investigate a different factor su…

Shock-augmented ignition (SAI) [R. H. H. Scott et al., Phys. Rev. Lett. 129, 195001 (2022)] is an alternative inertial confinement fusion concept that is designed to achieve high energy gain by combining improved resilience to instabilities with enhanced fuel compression. In SAI, lower implosion vel…

Despite heat flux's role in regulating energy conversion in collisionless plasmas, its properties and evolution in the magnetosheath downstream of the Earth's bow shock are scarcely explored. We use Magnetospheric Multiscale in situ measurements to quantify and characterize the electron heat flux in…

The Jeans instability in an unmagnetized, collisionless self-gravitating plasma characterized by a kappa or Lorentzian velocity distribution is investigated in the framework of kinetic and fluid approaches. We have examined the role of suprathermality on the instability threshold wave number and gro…

This experimental work reinvestigates the breakdown voltage in air for electrode gaps ranging from 0.10 to 6.00µm. Rarely addressed in the literature of the field, a special focus is placed on varying the gas humidity and its direct impact on the breakdown voltage. For short distances (<2µm), the…

Edge-localized modes (ELMs) eject intense bursts of heat and particles that threaten plasma-facing components in fusion reactors. Nonlinear full-torus BOUT++ simulations show that turbulence-driven zonal magnetic fields (ZMFs) play an essential role in nonlinear ELM evolution by maintaining self-con…

Using particle-in-cell simulations to study nonrelativistic laser pulse propagation in an under-critical plasma, we identify a novel mechanism that occurs during the growth of turbulent magnetic loops: electron penetration heating. The loops have an electromagnetic left-hand chirality distinct from …

The outflow velocity of expanding deuterium-tritium (DT) fuel can become significant after the bangtime, approaching local ion thermal velocity when the inertial confinement fusion (ICF) hotspot surpasses the ignition threshold. Under such conditions, the conventional assumption of an isotropic targ…

While the behavior of virtual cathodes (VCs) in a space-charge limited gap in the absence of a magnetic field is well understood, it is less characterized for crossed-field gaps with perpendicular magnetic and electric fields. Thus, this study examines VC formation at steady state in a crossed-field…

The cyclotron resonance dynamics of ions in a uniform magnetic field under the action of a plane left-handed polarized wave is considered. The dynamics of initially slow ions is nonlinear: they periodically synchronously (regardless of the initial phase of interaction) gain and then lose energy. The…

We demonstrate the onset of Rayleigh-Bénard convection (RBC) near the fuel-ablator interface of inertial confinement fusion (ICF) implosion simulations for the scenario in which Rayleigh-Taylor or Richtmyer-Meshkov instabilities are suppressed. This convective heating within the cold fuel can degrad…

Energy injection and dissipation in nonequilibrium systems typically lock microscopic motion and collective flow into a coupled evolution. Our observations in electron-beam-driven dusty plasma reveal a distinct “kinetic decoupling” regime where this synchrony breaks down. While microscopic and colle…
