More Information
Summary:An apparatus for plasma control is disclosed. The apparatus comprises: a plasma generator comprising two electrodes, an anode and a cathode, configured to produce a plasma between the two electrodes; a solenoid coil disposed to surround the plasma and configured to produce a magnetic field parallel to a longitudinal axis between the two electrodes; and circuitry configured for allowing independent timing of the magnetic field with respect to the production of the plasma. A method for plasma control in a spectroscopy system and an optical emission spectrometer using said method are also disclosed.
