HYDROGEN FLASH LAMPS

Many hydrogen-filled lamps have been tested and the effect of each of several parameters on the intensity and shape of the radiation pulse determined. The parameters were gas pressure, type of gas (hydrogen or deuterium), tube voltage, and electrode gap distance. A flash lamp has been designed and built which is simple, inexpensive, and easily disassembled. Our results show that deuterium-filled tubes with 2 mm gaps emit about (65±10)% more photons per discharge than hydrogen-filled tubes operated under similar conditions. The parameters favorable for a high intensity discharge are large gap with deuterium gas - for a rapid discharge, high pressure and voltage. © 1968 The American Institute of Physics.
