The experimental tube required under the terms of this contract has been designed, built and characterized for voltage holdoff under pulsed charge conditions. This tube Type HY-5527 exhibited a total holdoff characteristic that was somewhat inferior to that of its predecessor - Type HY-5525. The difference is believed to be attributable to the first-stage holdoff of the HY-5527 which was low compared with that of the HY-5525. Arc damage during conditioning is proposed to account for the HY-5527s poorer first-stage holdoff. Data are also shown for the Type HY-5553, a three-stage device designed and built under a subsequent phase of the overall program. This tube exhibited a total holdoff characteristic that exceeded those of both the HY-5525 and the HY-5527 in the high pressure regime - the region of interest. Future plans call for further testing of the HY-5553 and another tube of a differing design that appears promising. On the basis of these tests another generation of tubes will be designed, built and characterized at high pulse repetition rates and high rates of anode current rise. Author
