Abstract: An X-ray tube rotating anode is cooled with a liquid metal functioning as a recirculated heat exchange fluid and/or a metal film in a gap between the anode and a stationary structure. The liquid metal is confined to the gap by (a) a labyrinth having a coating that is not wetted by the liquid, (b) a magnetic structure, or (c) a wick. The liquid metal recirculated through the anode is cooled in a heat exchanger located either outside the tube or in the tube so it is surrounded by the anode. The heat exchanger in the tube includes a mass of metal in thermal contact with the recirculating liquid metal and including numerous passages for a cooling fluid, e.g. water. A high thermal conductivity path is provided between an anode region bombarded by electrons and a central region of the tube where heat is extracted. In one embodiment the high thermal conductivity is achieved by stacked pyrolytic structures having crystalline axes arranged so there is high heat conductivity radially of the region and lower thermal heat conductivity normal to the high heat conductivity direction.

Abstract: Apparatus to perform correlation spectroscopy utilizes a zero dispersion monochromator having entrance, intermediate and exit slits. A ruled grating is located in the beam path between entrance and exit slits and is operable to disperse a beam of radiation incident thereon both prior and subsequent to radiation passage through the intermediate slit. A first axis is parallel to the grating rulings, the entrance and exit slits symmetrically disposed at opposite sides of a plane bisecting and normal to a line extending between the entrance and exit slits, the plane also passing through the intermediate slit. That axis is located to have intersection with and to extend at an angle .PSI. relative to a normal to the plane that passes through said intersection thereby to substantially eliminate spectral overlap. Further, an array of sets of slits is provided adjacent the intermediate slit position of the monochromator, the sets of slits in the array being successively movable into the focal plane at the intermediate slit position.
