BL-221 70 GC MAGNETRON PRODUCTION ENGINEERING MEASURE

Research continued on the BL-221 70 Gc mag etron. Three additional tubes, one with vac-ion pump and two representing the standard design, were constructed and tested. Shelf life information on all tubes built to date was compiled and comparative life test evaluation under oscillation conditions was initiated. Progress was made on the ceramic window assembly, the construction of test equipment, and anode hobbing facili ies. Au hor A - N4 AD-275 419Div. 25 U TISTPWH Bro n U.
