Evolution of laser-induced carbon particle breakdown in gas
We investigate the evolution of the laser-induced breakdown of a suspended micrometer-sized carbon particle at 460 torr N2 gas environment. An elliptical hot gas resulting from the ionizations of the ...

Enhancement of electric force by ion-neutral collisions
The measured force exerted on an ion flow by an electric field is found to be larger than the electric force that can be exerted if the ions are collisionless. In addition, the increase of the gas pre...

“Super-hot” (kinetic energy ~4–8 eV) and “hot” (kinetic energy ~0.3 eV) H atoms were detected in a surface wave (500 MHz) generated H2 plasma column, at pressure p=0.01 mbar, from the analysis of the H

, H
, and H
emission line profiles. These profiles were found to evolve from single Gaussian to bi-Gaussian toward the plasma column end. Population inversion between the levels 5
4 and 64 was detected. At pressure p=0.2 mbar, super-hot atoms were not detected and the temperature of the hot atoms was found to increase with the upper level principal quantum number.
