Abstract
A device to produce and test a thin film of excited gas or liquid comprising a helium resonance lamp having an emission at 584A and including a window in said lamp partially transparent to radiation at 584A. A chamber containing a gas mixture including helium surrounds the window. Windows are provided in the chamber adjacent the lamp window, said windows being transparent to emission emanating from the gas adjacent the lamp window when the lamp is excited by an RF source.
Claims6
A device to produce and test a thin film of excited gas or liquid comprising
- a helium resonance lamp having an emission at 584A;
- an elongated window in said lamp of a material and design to be partially transparent to radiation at 584A;
- a chamber surrounding said elongated window;
- means for supplying a predetermined gas mixture containing helium to said chamber;
- further windows located in the wall of said chamber adjacent to and spaced from said elongated window, said windows being transparent to emission emanating from the gas adjacent to the elongated window;
- and
- the atmosphere in the space between said elongated window and said further windows having a predetermined optical transmission characteristic.
