Influence of a pulsed electric field luminescence in the rare gases excited by ionizing radiation

Measurements were made of the variation in intensity of light emission from gases excited by ionizing radiation at the beginning and end of a pulsed electric field. The rare gases helium, neon, argon, krypton, and xenon were studied. They were excited by a beam of x rays. In the case of helium, neon, and argon, no variation in light intensity characteristic of recombination was observed, other than that already described in the literature and due to increased excitation by electrons accelerated by the pulsed field. However, the heavier rare gases behaved differently. At the beginning of the field pulse a very weak decrease in luminescence occurred, which was almost completely masked by the increase produced by the increased excitation caused by accelerated electrons. On the other hand, at the end of the field pulse there was a large increase in luminescence. This showed that in the case of krypton and xenon dissociative recombination plays an active role in the mechanism of luminescence. (M.C.G.)
