WESTINGHOUSE WL 6285 MAGNETRON: DESIGN AND PERFORMANCE. VOLUME 1. PART 2.
Abstract
The first interaction field pattern studies were made with a high power oscillator and a 1/8 inch rotating probe. Searching was limited to 1600 mc which is the upper range of our high power oscillator. Later holes were drilled in the back of each cavity of the anode to aid in searching for resonances. Several resonances were found in this manner which were missed with the 1/8 inch probe. It soon became apparent that the 1/8 inch probe was not yielding sufficient resolution necessary to identify other than the pi mode patterns. The optimum length of probe for maximum detail was found to be slightly more than 1/2 inch for actual Model A cathode (1.170 inch diameter). With this length of probe affording greater signal pickup, it became practical to use a low power oscillator with an upper frequency limit of 3000 mc to search for resonances. Although a substantial portion of the cold field pattern work on Model A anode is completed a few vital tasks remain to be done before the anode is suitable for hot tests. (Author)
