Abstract
A non-perforated metal tube with open opposite ends extends coaxially around a plasma discharge tube that projects beyond both ends of the metal tube. The plasma tube contains an ionizable gas and an electrode. The ends of both tubes engage two end cap assemblies which maintain the tubes in a coaxial, uniformly spaced relationship. Both end cap assemblies have a tubular coupling that fits around a flared end of the metal tube and have a mechanism for supporting the glass tube. Passages are provided in the end cap assemblies for gas to enter and exit. A plasma is established in the plasma discharge tube by applying an excitation potential between the electrode and the metal tube.
