Electrode for flash discharge lamps
Abstract
The invention relates to an electrode for flash discharge lamps. The electrode is made from a substrate metal containing vanadium and an electron-emitting material from barium aluminate, thorium oxide, or a mixture therefore by shaping into a rod form and sintering. The electrodes are installed 25 mm apart inside a Pyrex glass tube and xenon gas is filled into the tube until the pressure reaches 400 mmHg and sealed. This improves the luminous efficacy.
