    Notes: A new rf source producing a large and uniform plasma with magnetic field-free geometry for neutral beam has been developed. The source consists of a small-diameter multiple-rf plasma generator and a bucket chamber as a plasma expansion section. The plasma density scaling, the spatial profile, and the ion beam extraction have been studied by using the single rf plasma generator. It was found that under the optimized conditions the plasma density and the profile in the expanded plasma were essentially ruled by qualities of the bucket chamber itself. The present rf source is promising for the application of large-volume positive-ion source or plasma processing.

    A new Zn|AlCl3|MnO2 galvanic cell suitable to water-activation (1990)
    Springer

    Notes: Abstract The Zn|3m AlCl3 (aq)|MnO2 galvanic cell gives an open circuit voltage (OCV) of 2.0V. When the cell is discharged at constant current (1.5 mA cm−2 or 50 mAg−1), its discharge curve shows a relatively flat portion in the region 2.0–1.6 V and the cell has an energy density of 550 Wh (kg of MnO2)−1 with a discharge capacity of 330 mA (kg of MnO2)−1, these values being about 2 times and 1.5 times, respectively, larger than those of the Zn|5m ZnCl2|MnO2 cell. The cell also shows good discharge behaviour at higher electric currents (for example 9.5 mAcm−2 or 240 mAg−1), and the advantages of the Zn|AlCl3|MnO2 cell over the Zn|ZnCl2|MnO2 are clear at the higher discharge currents. The high discharge voltage, energy density, and discharge capacity of the Zn|AlCl3|MnO2 cell are attributed to the strong buffering effect of AlCl3 at pH∼3. Due to this buffering effect, the electrolytic solution causes gradual corrosion of the zinc and, consequently, the cell is suited to water-activation.
