<p>A device for producing and controlling the flow rate of bubble-like ionization discontinuities (30) in a gas discharge tube (10) which includes means to produce an alternating current at a frequency between 1500 and 8000 Hz and a voltage between 2000 and 12000V (16), a capacitor (36) in series with the tube to prevent direct current flow through the tube, and means to produce asymmetry (18) between the positive portion and the negative portion of the alternating current through the tube, the asymmetry being time asymmetry or wave shape asymmetry, the degree of asymmetry influencing the rate of apparent bubble flow through the tube and the direction or asymmetry influencing the direction of the apparent bubble flow through the tube.</p> |
