Abstract : Two versions of the tube were developed. The first uses a Willemite screen (P-1) which gives a green trace and has medium persistence. The second uses a long-persistence cascade phosphor (P-7). The tube envelope consists of lead glass (Corning 0120) except for the face plate, which is made of Fourco glass. A modified small-button 9-pin stem is used. Electrostatic focus and deflection are utilized in the electron gun which is supported in the envelope by 4 support springs. The springs also serve to absorb shock and vibration. About 10% of the cathode current reaches the screen, and the rest is absorbed by the limiting apertures. The tube passed the vibration test and a 500-g shock test. Both versions of the tube suffered a burning of the phosphor screen during life tests. A life test period of 500 hr or less was considered to be more realistic than the 1000-hr test. The method of producing the tube is described. The tubes operated at LV, had good light output, and did not have an exposed exhaust tip.
