The response of collisionless plasmas to an applied potential can differ from classic Debye shielding, and when the potential is rapidly applied (“instantaneous shielding”), the shielding can differ from when it is slowly applied (“adiabatic shielding”). Experiments demonstrate that when a test potential well is applied to a one-dimensional pure-electron plasma, instantaneous and adiabatic shielding are similar for small potentials, but that instantaneous shielding is weaker than adiabatic…

Charge shielding in magnetized plasmas
The shielding of a charge sheet in a magnetized plasma is investigated by taking account of the diamagnetic drift start-up current in addition to the polarization current. For a charge sheet with an
Debye screening and injection of positrons across the magnetic surfaces of a pure electron plasma in a stellarator
Just as quasineutral plasmas, pure electron plasmas display collective behavior and screen externally imposed electrostatic potentials. However, for pure electron plasmas, the screening of large

Dynamic and Debye shielding and anti‐shielding
While shielding in collisional plasmas obeys the standard Debye result, shielding in collisionless plasmas is far more complex than commonly believed. For example, a one‐dimensional (highly
Dynamic and Debye shielding and antishielding in magnetized, collisionless plasmas.
TLDR
The new theory of dynamic shielding, developed herein, is in good agreement with experiments in pure electron plasmas and results solely from electrons dynamically trapped in the neighborhood of the test charge.
Plasma shielding, Vlasov's equation, and the unperturbed-orbits technique
Abstract The common textbook derivation of collisionless plasma shielding is technically invalid. Trapped particles are crucial to shielding, but the trapped-particle distribution does not reach a
Secular behavior of electrostatic Kelvin–Helmholtz (diocotron) modes coupled with plasma oscillations
Electrostatic instabilities in electron plasmas have been studied by analyzing initial value problems. The self-electric field of a non-neutral plasma produces a flow that brings about non-Hermitian
Effect of flow profile on low frequency drift-type waves in a dusty plasma
A nonlocal theory has been developed to study the effect of a flow profile on the stability of low frequency drift-type instability in an inhomogeneous, dusty plasma. The representative experimental
Long-Time Containment of a Pure Electron Plasma
A pure electron plasma has been confined in cylindrical geometry for many minutes. Confinement scalings with background pressure and magnetic field show that the maximum confinement times, while
