Abstract

Advances in the design of vacuum electronics devices through the use of a code with software cold-test capability-the 3-D electromagnetic code uSOS-are shown. Descriptions are then given of three circuit geometries that have undergone software cold-test using the uSOS frequency-domain solver. The first structure is a racetrack-shaped cavity commonly used in klystron. The second example is the output cavity of an extended interaction klystron. The third geometry is a typical millitron coupled cavity TWT (traveling-wave tube) circuit. Comparisons of information obtained via software cold-test to that obtained conventionally are shown. Software cold-test is seen to be effective and economical.<>
