Abstract
687,228. X-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 1, 1951 [March 4, 1950], No. 4987/51. Class 39(i) An X-ray tube for diffraction investigation has a double window: an outer one 8 of mica and an inner one 10 of beryllium or aluminium. An annular metal ring 6 is secured in the wall 1 of the tube, using a powdered glass sealing mixture 7 if the wall is of glass, and the mica window 8 hermetically sealed inside the ring 6 by a similar seal 9. The second window is a beryllium disc 10 of 0.1 to 0.15 mm. thickness, secured to a shoulder formed in the wall 1. The metal window prevents electrical charges from forming on the mica window, while the provision of the latter allows the use of a thinner metal window than otherwise.
