ABSTRACT:
A gas containing envelope in the form of a double walled cylinder is closed at one end and open at its other end, with the double walls of the cylinder defining an enclosed gas discharge area. The double walls of the cylinder are made of a transparent dielectric material such as glass. The gas discharge area formed between the double walls is filled with an ionizable gas, and an electrode is disposed adjacent to or within the gas discharge area between the cylinder walls at the closed end of the envelope cylinder. A ground potential reference point is provided outside the double walled cylinder, and a power supply is provided to couple an a.c. electrical signal between the electrode and the ground potential reference point for producing visible electrical discharges in said gas discharge area.
