A new design of a sealed rotating anode X-ray tube has been developed which has an X-ray emission power that is a factor of 1.4, 1.6, and 2.0 greater than present-day X-ray tubes operating respectively at 50, 150, and 300 kilovolts with the same targ

The image information transfer efficiency for five x‐ray fluorescent screens (calcium tungstate, barium halide, and three rare earth screens) has been experimentally determined with monoenergetic x‐ray beams at energies of 18, 22, 32, 49, 51, 58,

With monoenergetic x‐ray beams incident on polystyrene phantoms, the spectra of the transmitted x rays were measured with a scintillation spectrometer. The scattered and unscattered components of the transmitted x‐ray fluence at a point on the be

This work describes a new method for the experimental evaluation of antiscatter x-ray grids in radiography. Five commercial grids are evaluated in terms of two parameters which are determined only by the construction of the grid and the x-ray energy.

The differential cross section d sigma /sub K/, for the Compton scattering of 660-kev photons by the K-shell electrons of tin and gold, is determined by an experimental method in which a scattered photon is selected in coincidence with an accompanyin

With 200- and 400-keV electrons incident on thin targets of aluminum, copper, tin, and gold, experimental data are given for the pulse-height distributions produced in a silicon detector by the electrons scattered at angles of 40\ifmmode^\circ\else\t
