An investigation of shock formation versus shock mitigation of colliding plasma jets
Petr Cagas, James Juno, Ammar Hakim +4
This work studies the interaction between colliding plasma jets to understand regimes in which jet merging results in shock formation versus regimes in which the shock formation is…
Continuum kinetic investigation of the impact of bias potentials in the current saturation regime on sheath formation
Chirag R. Skolar, Kolter Bradshaw, James Juno +1
In this work, we examine sheath formation in the presence of bias potentials in the current saturation regime for pulsed power fusion experiments. It is important to understand how…
Resolving the mystery of electron perpendicular temperature spike in the plasma sheath
Yanzeng Zhang, Yuzhi Li, Bhuvana Srinivasan +1
A large family of plasmas has collisional mean-free-path much longer than the non-neutral sheath width, which scales with the plasma Debye length. The plasmas, particularly the ele…
Plasma sheath studies using a physical treatment of electron emission from a dielectric wall
Kolter Bradshaw, Petr Cagas, Ammar Hakim +1
When a plasma sheath forms next to a dielectric wall, material properties determine electron absorption and reflection from the surface, impacting the sheath formation and structur…
A kinetic interpretation of the classical Rayleigh-Taylor instability
John Rodman, Petr Cagas, Ammar Hakim +1
Rayleigh-Taylor (RT) instabilities are prevalent in many physical regimes ranging from astrophysical to laboratory plasmas and have primarily been studied using fluid models, the m…
Bohm criterion of plasma sheaths away from asymptotic limit
Yuzhi Li, Bhuvana Srinivasan, Yanzeng Zhang +1
The plasma exit flow speed at the sheath entrance is constrained by the Bohm criterion. The so-called Bohm speed regulates the plasma particle and power exhaust fluxes to the wall,…
