An injector has been built at the University of Maryland which produces a hollow cylindrical beam of relativistic electrons. The design uses a low-impedance pulse generator and step-up, transmission-linetransformer to drive a high-impedance, field-emission electron gun. This paper reviews the design of the pulse generator and performance of the pressurized gas switches. The transformer and electron gun design is also described and results are given for the initial tests of the injector with a 2-MeV, 6-kA beam.

The transient analysis of nonuniform transmission lines is a task that has to be done frequently in varied fields of engineering. Since the analytical solutions exist only in a few cases, numerical algorithms become inevitable. This short paper describes a new and simple method of the transient response calculation of nonuniform transmission lines. The new approach uses the electrical distance as an independent variable, and makes it possible to apply the method of characteristics as easily as in the case of uniform lines. The technique is thus more practical than those previously described.
A multivariable array is developed by means of which the realizability conditions for the n-variable low-pass ladder network are obtained. By means of suitable transformations, other types of n-variable ladder network...
