Dense capillary discharge plasma waveguide containing Ag ions
Abstract
Interferometry of plasmas generated by fast discharge excitation of Ag2S microcapillary channels shows the formation of dense plasma waveguides capable of guiding intense laser beams. Discharge ablation of capillaries, 330 μm or 440 μm in diameter, with 3-5.5-kA current pulses formed concave plasma density profiles with axial electron density >1 × 1019 cm-3. These dense plasma waveguides containing highly ionized metal atoms are of interest to the development of a longitudinally pumped soft X-ray lasers.

The radio-frequency plasma potential in a stove top inductively coupled plasma source is measured by a capacitive probe. The experimental results are compared to a crude circuit model which accounts for capacitive coupling ... -
Anisotropic plasma-chemical etching by an electron-beam-generated plasma
Anisotropic etching of SiO2 has been achieved with a plasma generated by a broad-area low-energy (150-300 eV) electron beam in a He + CF4 atmosphere. Etch rates of up to 330 Å/min for SiO2 and 220 Å/min for Si were obtained. ...
