Research and Development Program on a Miniature X-Band Pulsed Magnetron (MA208) Third Quarterly Progress Report 1 April, 1958 to 1 July, 1958

摘要

A description of the research and development work done en the MA208 tunable magnetron during the third quarter is given. Results of “cold tests” on a new tuner crown utilizing a ceramic insulating base are presented. Low level test results on a combination L-C type timer crown are described in the report, The effects of a design change in the output section are noted which indicate further work is required to prop¬erly notch the high end of tuning band. Cathode and magnet design charges are discussed. Results of oper¬ating life tests are presented. An illustration show¬ing the outline configuration of the MA208 with the new magnet design is included.
