Abstract:

This analysis is concerned mainly with oscillations and fluctuations which occur either spontaneously, or as a result of deliberate excitation, in low-pressure, hot-cathode plasmas. Experimental observations on high and low frequency effects occurring spontaneously are discussed, and speculations are made on the possible gener-ATION MECHANISMS. In many cases, theories of these mechanisms have been treated in experiments involving deliberate excitation of oscillations, and comparisons are made where relevant. For device applications, and to relieve the difficulties which occur in quantitative experiments in plasma physics, it is important that the sources of spontaneous oscillations should be understood and suppressed if possible. The analysis includes a discussion of work which has been carried out to reduce these effects, and concludes with some suggestions for further lines of attack on the problems. Author
