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.
Claims26
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 turn and a second turn to provide an inner aperture formed from the first and second turns of the coil, 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 turn of the coil and a second radial fin coupled to the second turn of the coil, in which the coil is configured to provide radio frequency energy to the body of the torch to sustain the ionization source within the torch;
- and
- a spacer coupled to the first radial fin of the first turn of the coil and to the second radial fin of the second turn of the coil.
