INVESTIGATION OF MICROWAVE DUPLEXER SWITCHING MECHANISMS
Abstract
The study of the velocity of the discontinuities produced at the end of a tube by a high power RF pulse and propagating in a plasma was continued. A new geometry, characterized y a variation in the cross section of the tube, was tested. A new pertur ation, propagating at an unusually high velocity, was identified as a shock wave. Its velocity is in close agreement with that predicted by the theory. Experiments, involving the known phenomenon of charge exchange collisions between particles with different ionization potential, were performed to determine the sonic or ionic wave character of observed discontinuities. The propagation velocity of the discontinuities in pure gases and pure gases admixed with small amount of impurities was compared. In some gas mixtures, a decrease of the velocity towards the sound velocity in the impurity gas at room temperature was observed, but this result is not evident enough to assert the presence of an ionic wave in the plasma. The qualitative theory is given and the results are discussed. (Author)
