Rapid Start, High Average Power BLT Switch for Anti-Missile Radar

Abstract

The Back Lighted Thyratron with a Super- the pulse, there is no conceivable way to absorb or disperse Emissive Cathode (BLT-SEC) has unique advantages of it contemporaneously with its generation. Fig. 1 shows the high peak current, small size, very low heater power, and heat penetration into tungsten at the end of a single 500 ns prompt warm-up compared to conventional hydrogen pulse of 107 W 1 cm2. thyratrons. These characteristics make it suitable for many modern applications such as anti-missile radar, space borne weapons systems, pollution control pulse generators, and industriallasers.1 We report advances made in the understanding of electrode erosion and average power heating, and describe "rotary firing," a novel method for improving tube life and average power ratings.
