Measuring the plasma density of a ferroelectric plasma source in an expanding plasma [PDF]

Journal of Applied Physics, 2004
The initial density and electron temperature at the surface of a ferroelectric plasma source were deduced from floating probe measurements in an expanding plasma. The method exploits negative charging of the floating probe capacitance by fast flows before the expanding plasma reaches the probe.

Experimental Investigations of Magnetohydrodynamic Plasma Jets [PDF]

, 2009
This thesis primarily focuses on understanding the plasma behavior during the helicity injection stage of a pulsed spheromak experiment. Spheromak formation consists of a series of dynamic steps whereby highly localized plasma near the electrodes evolves

Collimated fast electron beam generation in critical density plasma [PDF]

, 2014
Significantly collimated fast electron beam with a divergence angle 10° (FWHM) is observed when an ultra-intense laser pulse (I = 1014 W/cm2, 300 fs) irradiates a uniform critical density plasma. The uniform plasma is created through the ionization of an

Detailed H(n=2) density measurements in a magnetized hydrogen plasma jet [PDF]

, 2012
We present detailed spatial density measurements of H(n = 2), i.e. the first excited state of atomic hydrogen, in a hydrogen plasma expansion that is weakly magnetized. At a specific distance from the source of the expansion a sharp transition from a red

Comparison between electropositive and electronegative cold atmospheric-pressure plasmas: a modelling study

High Voltage, 2016
Cold atmospheric-pressure He + N(2) and He + O(2) plasmas are chosen as the representatives for electropositive and electronegative plasmas, of which the discharge characteristics are studied and then compared to each other by fluid models.
