摘要： A system and method are provided for delivering power to a dynamic load. The system includes a power supply providing DC power having a substantially constant power open loop response, a power amplifier for converting the DC power to RF power, a sensor for measuring voltage, current and phase angle between voltage and current vectors associated with the RF power, an electrically controllable impedance matching system to modify the impedance of the power amplifier to at least a substantially matched impedance of a dynamic load, and a controller for controlling the electrically controllable impedance matching system. The system further includes a sensor calibration measuring module for determining power delivered by the power amplifier, an electronic matching system calibration module for determining power delivered to a dynamic load, and a power dissipation module for calculating power dissipated in the electrically controllable impedance matching system.

Applications for the system and method are also disclosed for detecting volatile organic compounds in trace concentrations. A microwave or high-frequency RF energy source ionizes particles of a reagent vapor to form reagent ions. The reagent ions enter a chamber, such as a drift chamber, to interact with a fluid sample. An electric field directs the reagent ions and facilitates an interaction with the fluid sample to form product ions.

摘要： A system, components thereof, and methods are described for time-of-flight mass spectrometry. A microwave or high-frequency RF energy source is used to ionize a reagent vapor to form reagent ions. The reagent ions enter a chamber and interact with a fluid sample to form product ions. The reagent ions and product ions are directed to a time-of-flight mass spectrometer module for detection and determination of a mass value for the ions. The time-of-flight mass spectrometer module can include an optical system and an ion beam adjuster for focusing, interrupting, or altering a flow of reagent and product ions according to a specified pattern. The time-of-flight mass spectrometer module can include signal processing techniques to collect and analyze an acquired signal, for example, using statistical signal processing, such as maximum likelihood signal processing.

摘要： The invention features an RF plasma generator. The RF plasma generator includes a variable frequency RF generator, comprising an H-bridge and an RF output. The RF generator generates electromagnetic radiation having a power. The RF plasma generator further includes a matching network that includes at least one variable impedance component. The matching network also includes a first port that is electromagnetically coupled to the output of the RF generator and a second port. The RF plasma generator also includes a load that is electromagnetically coupled to the second port of the matching network, and a plasma chamber for containing a plasma having a power. The plasma chamber is electromagnetically coupled to the load and receives electromagnetic radiation having a power from the load. Adjusting at least one of the frequency of the RF generator and the variable impedance component in the matching network changes the power in the plasma.
