Abstract
Systems and methods are disclosed for exhausting and combined exhausting and seasoning of x-ray tubes having glass envelopes for high performance x-ray system having a rotating anode therein. The system and methods include providing a glass tubulation having a diameter greater than about 20 mm; then operatively connecting the glass tubulation to the x-ray tube glass envelope; providing a metal disk inside the glass tubulation, the metal disk having a smaller diameter than the glass tubulation, providing a vacuum to the glass tubulation; heating the anode of the x-ray tube to a temperature inside the x-ray tube envelope of about 1500.degree. C.; positioning a heater on the outside of the glass tubulation; positioning the metal disk inside the glass tubulation proximate the position of the heater on the outside of the glass tubulation; heating the metal disk to a sufficient temperature to provide for contact between the glass tubulation and the metal sealing disk; and checking for sealing contact between the glass tubulation and the metal disk thereby sealing the glass tubulation/metal disk envelope connection.
