Efforts were continued on a PEM Program to in vestigate minor constructional modifications in the present 70 Gc BL-221 magnetron design and to set-up a manufacturing facility capable of pro ducing at a rate of fifty 50 tubes per month. Operational life tests on two magnetrons having ceramic windows were conducted. The first hob was manufactured using the hob grinding machine and associated facilities. Evaluation of 10 tubes using anodes made with the above facilities was completed. Work was continued on soft tube modulators and modification of cathode centering mechanism. Humidity-temperature tests were continued. Author
