| Popis: |
An experimental study is made of the interaction of pulsed microwaves in the 10 cm range with collisionless plasma flows (ω ≫ ν) in a waveguide under both favorable (▽n ‖ E, ω ≈ ωLe) unfavorable initial conditions for plasma resonance of the waves. It is shown that in the first case over the interval vE/vTe = 10-5-5 the absorption coefficient D2 changes little while absorption sets in almost immediately (t < 0.01 µsec) and is accompanied by rapid decay of the plasma and the production of fast electrons. In the second case (▽n ⊥ E) anomalously strong absorption sets in after a time delay (tdelay = 1-3 µsec) related to the time for the leading edge of the plasma to become deformed when the wave pressure exceeds the plasma pressure (E 0 2 /8π ≳ neTe). |
