1970 Proc. Inst. Electr. Engineers 117 1060/2 A subnanosecond voltage step is generated by short-circuiting a charged transmission line with a krytron. This 4-element valve, comprising an anode, radioactive cathode, ignition grid and keep-alive electrode, is designed to work in an arc-discharge mode.
1975 Rev. Sci. Instruments 46 1333/1 The new krytron-switched Blumlein circuit has demonstrated a significant improvement in performance over the spark gap circuit.
1985 Science 14 June 1293/1 High-speed electronic switches known as krytrons.
1990 Daily Tel. 4 Apr. 3/7 In a [nuclear] bomb, a capacitor would be used to dump a large pulse of electricity through a high-speed switch like a krytron to set off the conventional explosives used to detonate the weapon.
