Abstract:

The use of the resonant cavity method for measuring electron densities and collision frequencies in the ionized wakes of hypervelocity pellets is described. The equivalent circuit obtained from a normal mode analysis of the cavity fields and their interaction with the wake plasma is used to determine the plasma parameters in terms of measurable properties of the cavity. The range of validity of the method is discussed, along with a sensitivity and accuracy analysis.
