Abstract: A microwave system has a solid-state generator which generates microwave energy and includes at least one control input for receiving a control signal to vary electrically a parameter of the microwave energy. A microwave load receives the microwave energy and produces an effect in response to the microwave energy. A microwave conducting element couples the microwave energy to the microwave load. An impedance match adjusting device is coupled to the microwave conducting element to vary at least one of the parameters of the microwave energy. The effect produced in response to the microwave energy is altered by both electrical variation of the parameter of the microwave energy via the control signal and adjustment of the impedance match adjusting device to vary the parameter of the microwave energy.

Abstract: An apparatus and method for determining the health of a plasma system by igniting a plasma within a plasma confining volume generate an ignition signal with an ignition circuit and apply the ignition signal between a biased region and a grounded region in the vicinity of the plasma confining volume. A parameter in the ignition circuit is sensed, and the sensed parameter is compared to a first parameter threshold. A condition associated with the plasma confining volume is determined if the sensed parameter differs from the first voltage threshold, and a corrective action can be taken.
