ABSTRACT:
A curved discharge tube is manufactured by preparing a straight quartz tube having an eccentric longitudinal opening and then bending the heated tube into a current tube with a thicker waall portion of the tube on the outside and the thinner wall portion on the inner side. It is advantageous to seal inner gas into the tube before bending so as to obtain a curved tube having uniform wall thickness.
