MINIMUM RISE TIMES OF CURRENT IN IGNITRONS
Technical Report
·
OSTI ID:4024289
A pulse modulator switch was needed to carry currents beyond the ratings of the largest thyratrons and with a very rapid rise time. It also had to have a long life. Therefore, ignitrons were tested to determine their minimum current rise times. In these tests grided and ungrided tubes were used to short-circuit the coaxial cable pulse lines. The results showed ignitrons do not conduct current fast enough for the application. Tube temperature was confirmed to be the dominant parameter; circuit impedance snd current had little effect in the ranges investigated. Several mechanisms which slow the current rise are discussed, and gas breakdown speed is concluded to be the limiting factor rather than tube inductance. (auth)
