Abstract

An RF power variable capacitor capable of operating at at least 50 watts in the MHz range. The capacitor has a composite HDK-NDK ceramic dielectric. The HDK (high dielectric constant) component comprises an active matrix of barium strontium titanate, for example. Acoustic resonances are reduced or eliminated by the addition of a metal or metalloid oxide such as magnesium borate (NDK – low dielectric constant), which acts as an acoustic resonance reduction agent (ARRA) in the RF power domain. The acoustic resonances which previously occurred under bias voltage 500 V (curve 25) or 1100 V (curve 26) in prior art RF power variable capacitors are eliminated by the addition of the ARRA (curves 22 and 21).

Abstract

A variable vacuum capacitor is described in which oil inside the main bellows (21) is pumped through the bellows and through the oil circuit (8) of a heat exchanger by a pump (15). Water passes through coolant channels (6) of the heat exchanger, from inlet (7) to outlet (7′). The extendable capacitor drive shaft (14) is hollow and serves as a conduit, conveying the oil to the bottom of the (bellows 21), thereby ensuring a full circulation of the oil right through the bellows and then through the heat exchanger. Pump drive means (9) may be a gerotor hydraulic motor, coupled to a gerotor oil pump (15) via magnetic coupling (22). Pumping heat transfer fluid (oil) through the bellows allows the capacitor to operate at significantly higher currents and/or lower temperatures, and significantly extends the life of the device.

Abstract

The present invention proposes a novel X-ray cathode head design, thanks to which the alignment of the filament with the focusing cup is facilitated. In particular, it proposes an X-ray cathode head in which filament and focusing cup are self-aligning upon assembly. The goal of the invention is achieved with an X-ray cathode head comprising a filament, supported by a filament support part, a focusing cup with an extraction slit integrated its center. Upon assembly of the focusing cup with the filament support part, the filament and the extraction slit are translationally and rotationally self-aligning, resulting in the alignment of both short and long axes of the filament and of the extraction slit.

The invention describes a method of frequency tuning an electrical generator (100) for supplying electrical power to a plasma, wherein the method comprises a pulsed mode, the pulse mode comprising at least a high power pulse (314) comprising a high power level (304) and a low power pulse (312) comprising a low power level (302) different to zero power, the method comprising the steps of: - providing RF-power with a high power starting frequency set comprising at least one high power starting frequency (502, 504, 506) at the high power pulse (314) with a predefined high power pulse shape; - providing RF-power with a low power starting frequency set comprising at least one low power starting frequency (512, 514) at the low power pulse (312) with a predefined low power pulse shape; - determining a reflected high power at the high power starting frequency (502, 504, 506); - tuning the high power starting frequency (502, 504, 506) to a different first high power frequency if the reflected high power exceeds a high power threshold value such that the reflected high power decreases below the high power threshold value; - determining a reflected low power at the low power starting frequency (512, 514); - tuning the low power starting frequency (512, 514) to a different first low power frequency if the reflected low power exceeds a low power threshold value such that the reflected low power decreases below the low power threshold value. The invention further describes a corresponding electrical generator (100), plasma processing system and computer program product. The method, the electrical generator, the plasma processing system and the computer program product may have the advantage that the stability of the plasma with respect to repeated and essentially identical high and low power pulses is used to reduce the controlling effort and to check the stability of the plasma process.
