Staged cooling of a fusion-grade plasma in a tokamak thermal quench
Jun Li, Yanzeng Zhang, Xian-Zhu Tang
In tokamak disruptions where the magnetic connection length becomes comparable to or even shorter than the plasma mean-free-path, parallel transport can dominate the energy loss an…
On the collisional damping of plasma velocity space instabilities
Yanzeng Zhang, Xian-Zhu Tang
For plasma velocity space instabilities driven by particle distributions significantly deviated from a Maxwellian, weak collisions can damp the instabilities by an amount that is s…
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…
Cooling flow regime of a plasma thermal quench
Yanzeng Zhang, Jun Li, Xian-Zhu Tang
A large class of Laboratory, Space, and Astrophysical plasmas is nearly collisionless. When a localized energy or particle sink, for example, in the form of a radiative cooling spo…
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,…
