An electrodeless fluorescent lamp includes a feedthrough structure extending from the exterior to the interior of the lamp which is constructed of a suitable material, e.g., platinum or a combination of platinum and rhodium, for directly connecting an interior EMI shield to ground. The feedthrough is also suitable for supporting an amalgam flag.

Electrodeless fluorescent lamp having feedthrough for direct connection

Improved methods of exhausting and combined exhausting and seasoning of x-ray tube envelopes for high performance x-ray system having a rotating anode therein which includes providing a glass tubulation having a diameter greater than about 20 mm then operatively connecting the glass tubulation to the x-ray tube envelope, providing a disk inside the glass tubulation, the disk having a smaller diameter than the glass tubulation, providing a vacuum to the glass tubulation; positioning heating means on the outside of the glass tubulation, heating the anode of the x-ray tube to a temperature temperatures inside the x-ray tube envelope of about 1500.degree. C., positioning the disk inside the glass tubulation proximate the position of the heating means on the outside of the glass tubulation, heating the glass tubulation proximate the disk to about 1300.degree. C., checking for sealing contact between the glass tubulation and the disk; and cooling the glass tubulation proximate the disk until the temperature of the heated area is below about 300.degree. C., thereby sealing the tubulation/envelope connection are disclosed.

Method for manufacturing x-ray tubes

Systems and methods are disclosed for exhausting and combined exhausting and seasoning of x-ray tubes having glass envelopes for a high performance x-ray system having a rotating anode therein. The 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 glass sealing cup inside the glass tubulation, the glass sealing cup having a smaller diameter than the glass tubulation, providing a vacuum to the glass tubulation, positioning a heater on the outside of the glass tubulation, heating the anode of the x-ray tube to a temperature inside the x-ray tube glass envelope of about 1500.degree. C., positioning the glass sealing cup inside the glass tubulation proximate the position of the heating means on the outside of the glass tubulation, heating the glass tubulation proximate the glass sealing cup to about 1300.degree. C., checking for sealing contact between the glass tubulation and the glass sealing cup; and cooling the glass tubulation proximate the glass sealing cup until the temperature of the heated area is below about 300.degree. C., thereby sealing the glass tubulation/glass sealing cup glass envelope connection.

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.

System and method for manufacturing x-ray tubes having glass envelopes

A system for sealing a large diameter tube under vacuum including: a tube having a diameter greater than about 20 mm, a disk operatively positioned inside the tube and having a smaller diameter than the tube, a vacuum operatively connected to the tube, heating means, operatively positioned on the outside of the tube, for heating the tube to a temperature sufficient to collapse the tube onto the disk, means for positioning the disk inside the tube proximate the position of the heating means on the outside of the tube and means for cooling the tube proximate the disk sufficiently to formulate a seal between the tube and the disk where the disk collapsed onto the disk is disclosed.
