Biased electrodes are common components of plasma sources and diagnostics. The plasma–
electrode interaction is mediated by an intervening sheath structure that influences …

In the inductively coupled plasma of the Njord helicon device we have, for the same
parameters as for which an ion beam exists, measured a downstream population of high …

The generalized Bohm criterion is revisited in the context of incorporating kinetic effects of
the electron and ion distribution functions into the theory. The underlying assumptions and …

Non-equilibrium distribution functions of electrons and ions play an important role in plasma
physics. A prominent example is the kinetic Bohm criterion. Since its first introduction it has …

Both Laser-Induced Fluorescence (LIF) and Retarding Field Energy Analyzers (RFEA) have
been applied to the investigation of beams formed in inductively coupled helicon plasmas …

The charging of a sounding rocket in subsonic and supersonic plasma flows with external
magnetic field is studied with numerical particle‐in‐cell (PIC) simulations. A weakly …

Interaction of plasma with finite-sized objects is one of central problems in the physics of
plas-mas. Since object charging is often nonlinear and involved, it is advisable to address …

The spatial evolution of the 1 s 5 metastable argon atom velocity distribution function is
recorded in the sheath and pre-sheath regions of a metallic wall using laser induced …

The formation time of the surrounding sheath of Langmuir probes in an ionospheric plasma
has been studied to better understand the constraints this puts on the sampling frequency of …

In his comment, Riemann defends the conventional kinetic Bohm criterion (KBC) on the
basis that the underlying approximations become rigorous in the limit λ D/l→ 0, where λ D is …
