Graphite-ceramic rf Faraday-thermal shield and plasma limiter

Patent Hwang, D L.Q.; Hosea, J C

The present invention is directed to a brazing procedure for joining a ceramic or glass material (e.g., Al/sub 2/O/sub 3/ or Macor) to graphite. In particular, the present invention is directed to a novel brazing procedure for the production of a brazed ceramic graphite product useful as a Faraday shield. The brazed ceramic graphite Faraday shield of the present invention may be used in Magnetic Fusion Devices (e.g., Princeton Large Torus Tokamak) or other high temperature resistant apparatus.
Modified eddy current probe having a faraday shield

Patent Moore, James A.; Emery, Michael S.; Simpson, Marc L.; ...

A modified eddy current (MEC) probe includes a probe body having a bore formed therein. A printed circuit board (PCB) assembly includes a circuit board defining a plane, has a plurality of electronic components mounted thereon, and is configured for mounting within the bore of the probe body. A coil board assembly is electrically connected to the PCB assembly, defines a plane, and includes a first coil board layer, a second coil board layer bonded to the first coil board layer, a transmitter coil formed on an outside surface of the first coil board layer, a Faraday shield formed onmore »« less

Production of stable, non-thermal atmospheric pressure rf capacitive plasmas using gases other than helium or neon

Patent Park, Jaeyoung; Henins, Ivars

The present invention enables the production of stable, steady state, non-thermal atmospheric pressure rf capacitive .alpha.-mode plasmas using gases other than helium and neon. In particular, the current invention generates and maintains stable, steady-state, non-thermal atmospheric pressure rf .alpha.-mode plasmas using pure argon or argon with reactive gas mixtures, pure oxygen or air. By replacing rare and expensive helium with more readily available gases, this invention makes it more economical to use atmospheric pressure rf .alpha.-mode plasmas for various materials processing applications.

Plasma sweeper to control the coupling of RF power to a magnetically confined plasma

Patent Motley, Robert W [Princeton, NJ]; Glanz, James [Lawrenceville, NJ]

A device for coupling RF power (a plasma sweeper) from a phased waveguide array for introducing RF power to a plasma having a magnetic field associated therewith comprises at least one electrode positioned near the plasma and near the phased waveguide array; and a potential source coupled to the electrode for generating a static electric field at the electrode directed into the plasma and having a component substantially perpendicular to the plasma magnetic field such that a non-zero vector cross-product of the electric and magnetic fields exerts a force on the plasma causing the plasma to drift.
