Notizen: A time-of-flight analyzer has successfully been used to measure the extracted charge-state distribution and impurity level of an ECRH mirror plasma. End-loss temperatures for each ion species have been determined from the rise time of the analyzer output pulses. Ions entering the line-of-sight device are first accelerated by a two-aperture lens and are then focused with an einzel lens. Electrostatic deflection plates chop the ion beam into short pulses which travel down a 1.20-m tube to an electron multiplier. Ion spectra are typically summed at a rate of 1 kHz using a hardware signal averager.

Notizen: A high-power radio-frequency plasma source was built and tested for an antenna frequency of 2.45 MHz. A puff valve fed hydrogen gas into a plasma chamber made from 4-in.-diam Pyrex tubing. A helical antenna was wound directly around this chamber. The plasma source was surrounded by a magnetic bucket which used a longitudinal line-cusp geometry. For 20 kW of rf input power, the peak electron density was 2.0×1019 m−3, the electron temperature was 2.0 eV, the ion temperature was 0.9 eV, and the atomic hydrogen density was 4.4×1019 m−3. For 90 kW of rf input power, the peak electron density was 8.9×1019 m−3, the electron temperature was 2.5 eV, the ion temperature was 3.0 eV, and the atomic hydrogen density was 2.3×1019 m−3. The plasma source had a typical current efficiency of 6 A/kW. A theoretical model for the plasma loading resistance was developed.
