Abstract
A device for sustaining a plasma in a torch is provided. In certain examples, the device comprises a first electrode configured to couple to a power source and constructed and arranged to provide a loop current along a radial plane of the torch. In some examples, the radial plane of the torch is substantially perpendicular to a longitudinal axis of the torch.
Claims22
A device for generating a plasma in a torch having a longitudinal axis along which a flow of gas is introduced during operation of the torch and having a radial plane substantially perpendicular to the longitudinal axis of the torch, the device comprising a first electrode configured to couple to a power source and constructed and arranged to provide a loop current along the radial plane of the torch.
A device for generating a plasma in a torch having a longitudinal axis along which a flow of gas is introduced during operation of the torch and having a radial plane substantially perpendicular to the longitudinal axis of the torch, the device comprising means for providing a loop current along the radial plane of the torch.
A method of generating a plasma in a torch having a longitudinal axis and having a radial plane substantially perpendicular to the longitudinal axis of the torch, the method comprising:
- providing a gas flow along the longitudinal axis of the torch;
- igniting the gas flow in the torch;
- and
- providing a loop current along the radial plane to sustain a plasma in the torch.
A substantially symmetrical plasma produced by igniting a gas flow in a torch and providing a loop current along a radial plane substantially perpendicular to a longitudinal axis of the torch to sustain the substantially symmetrical plasma.
