The present invention relates to a method and structure for controlling plasma uniformity in plasma processing applications. Electron thermal conductivity parallel and perpendicular to magnetic field lines differs by orders of magnitude for low magnetic fields (on the order of 10 gauss). This property allows the directing of heat flux by controlling the magnetic field configuration independent of ions since the effect of modest magnetic fields upon the transport of ions themselves is minimal. Heat is preferentially conducted along magnetic field lines with electron temperatures on the order of 0.1 to 1 eV / cm being sufficient to drive kilowatt-level heat fluxes across areas typical of plasma processing source dimensions.

An apparatus for terminating a controlled-impedance cable using compliant electrical contacts to provide an interface to another device. The terminator includes a conductive ground block for securing the cable by its ground shield and providing a common ground. Once the cable is anchored in the ground block, the block face and cable ends are dressed to make a reliable electrical contact with the compliant signal contact that electrically connects the cable center conductor to the device. An insulating or conductive plate mounted to the ground block holds the signal contact and optional ground contacts that electrically connect the ground block to the ground plane of the device. The ground contacts surround the signal contact in a pattern that closely mimics the impedance environment of the cable. When using a conductive plate, the signal contact is insulated from the plate by an insulating centering plug or a non-conductive coating.

A method for coupling ends of two insulated conductors includes coupling an end portion of a core of a first insulated conductor to an end portion of a core of a second insulated conductor. At least a part of the end portions of the cores are at least partially exposed. Electrically insulating material is placed over the exposed portions of the cores. A sleeve is placed over end portions of the two insulated conductors to be coupled. The sleeve includes one or more raised portions. The end portions include the exposed portions of the cores. The sleeve is coupled to jackets of the insulated conductors. The raised portions of the sleeve are mechanically compressed until the raised portions of the sleeve have a diameter substantially similar to a remainder of the sleeve. The compression of the raised portions of the sleeve compacts the electrically insulating material inside the sleeve.

A waterproofing method is provided for a wire to be arranged in a water susceptible area of a vehicle. The method includes removing an insulating coating layer in a lengthwise intermediate part of the wire to expose a core. A fluid waterproofing agent then is dropped to an exposed core section. Negative pressure then is introduced into the inside of the insulating coating layer from wire ends to suck the waterproofing agent into the inside of the insulating coating layer. Alternatively the exposed core section is loaded with pressure air to press the waterproofing agent into the inside of the insulating coating layer. Thus the waterproofing agent is infiltrated between the strands inside the insulating coating layer.
