Induction devices and methods of using them

摘要

Certain embodiments described herein are directed to induction devices that can be used to sustain a plasma. In certain configurations, the induction device may comprise one or more radial fins electrically coupled to a base. The induction device may take numerous forms including, for example, coils and plate electrodes.

主权项

1. A device for sustaining an ionization source in a torch comprising a longitudinal axis along which a flow of gas is introduced during operation of the torch, the device comprising:
a base configured to provide a coil comprising a first coil turn and a second coil turn to provide an inner aperture formed from the first and second coil turns, in which the inner aperture is constructed and arranged to receive a body of the torch; and a first radial fin coupled to the first coil turn and a second radial fin coupled to the second coil turn, in which the device is configured to provide radio frequency energy to the body of the torch to sustain the ionization source within the torch.
