The theoretical study of electrostatic waves was extended to include the finite extent of the plasma and external boundries. The plasma capacitor problem is presented to illustrate the effect of multiple reflections from the boundries. We show that only weak relfections are set up between open circuited grids. The normalized voltage transfer ratio is calculated for six different grid arrangements of double and triple grids. We operated the sodium plasma tube for two months and made DC density measurements which agreed with theoretical predictions. Noise measurements showed that no instabilities are present in our plasma and thereby we conclude that our plasma forms an excellent environment for electrostatic wave experiments. Author
