Abstract
A cold cathode arc discharge flash lamp has a cathode assembly in which an electron emissive pellet is secured on the lead wire or rod entering the flash tube envelope. One or more coils of molybdenum or a similar body of ceramic refractory shield the emissive face of the pellet from destructive ion bombardment while exposing the face for electron emission.
