Abstract
Official abstract text for this publication.
Certain embodiments described herein are directed to devices that can be used to sustain a capacitively coupled plasma. In some examples, a capacitive device can be used to sustain a capacitively coupled plasma in a torch in the absence of any substantial inductive coupling. In certain embodiments, a helium gas flow can be used with the capacitive device to sustain a capacitively coupled plasma.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device comprising: a torch; and a capacitive device external to and around at least a portion of the torch and contacting an outer surface of the torch, the capacitive device configured to provide radio frequency energy to the torch to sustain a capacitively coupled plasma in the torch, wherein the capacitive device comprises a wire coil external to and coiled around the torch, in which the wire coil is configured to couple to an oscillator at a fi…
