Abstract
A low pressure arc discharge tube having structural means located within the envelope for raising the voltage across the arc tube. The structural means comprises at least one partition extending across the arc tube and having a dimension which is less than the electron energy relaxation distance of the arc discharge tube. Each of the partitions has at least one aperture therein which constricts the arc within the tube.
