Abstract

PURPOSE:To obtain ultraviolet rays highly efficiently by satisfying the equation 4<=PXM<=40, where P is the sealing pressure (Torr) of rare gas and M is the mass (g) of the rare gas. CONSTITUTION:Multiple straight tube type lamps 2 are arranged in a flat plate type cavity 1, and a metal such as Hg is sealed in the lamps. The lamps 2 are made of ultraviolet ray permeating material such as quartz, and no electrode is required. The electric power is fed from a microwave power source 6 through a wave guide and a feed port 4. One face of the cavity 1 is formed with a metal mesh 3, through which the light is taken out. The sealing pressure P (Torr) of the rare gas of the lamp and the mass M (g) are selected to satisfy the equation 4<=PXM<=40. The energy loss due to the elastic collision between the rare gas of the plasma in the lamp and electrons can be then reduced, thus the output of ultraviolet rays is increased.
