Efforts were continued on a program to environ mentalize low noise traveling wave tubes. Two X-band tubes, M5059, Serials 10 and 16, were shipped during the period 1 June to 1 July 1963. A third tube, M5059, Serial 9, is ready for life testing. The pin-match problem, which delayed the L- and S-bandffffort, has continued to remain a problem. Some promising results were obtained on test vehicles, and vacuum envelopes using these results are now being processed. Author
