ABSTRACT:
An apparatus adapted for providing an aerodynamic window having a cylindrical configuration with an annular cross section capable of enveloping annularly a cavity therein is disclosed. The apparatus includes an annular injector adapted for providing a flow of first gas therefrom through a gas path having an annular cross section, an annular collector disposed in a spaced apart relation with the annular injector and adapted for collecting gas flowing through the gas path wherein the annular collector, the annular injector and the gas path cooperate to enclose a cavity therebetween and a gas insertion means for providing a flow of second gas within the cavity. In one embodiment electrodes disposed within the cavity are adapted for enhancing the energy level of the recipient elements of the second gas, as for example by ionization, to produce a high intensity light source. First gas passing through the flow path produces an aerodynamic window having an annular cross section capable of maintaining second gas within the cavity at a desired pressure level.
