This report describes the work done during the feasibility phase of a program to develop a low-noise, X-band traveling-wave tube capable of operating simultaneously as 1 a low-level linear output amplifier, 2 a highlevel limited output amplifier, and 3 a high-output video detector. The tube developed in this program was essentially a tube that could be tested and was designed to be amenable to many design changes. This approach enabled a thorough evaluation program with a minimum number of bottle starts. The work, reported in detail in this report, demonstrates the feasibility of the design approaches which were used to produce the desired tube. Two interim and three prototype tubes were delivered during this phase of the program. Data on the prototype tubes are given in the appendix to this report. Summaries of experimental results and conclusions are given throughout the body of the report. These data indicate that the performance of the multiple-function tube has indeed been demonstrated and that the desired tube design is highly feasible. The report ends with recommendations that are based on the conclusions given in the text.
