Abstract
A novel x-ray tube has been produced by using a line filament as a cathode. It is found that the electrons emitted form the filament arrive on the anode in a line perpendicular to the direction of the filament. The image of the x-ray emitting area on the anode obtained with a x-ray pinhole camera and a CCD detector shows a slightly curved line. The formation of this curved line is explained by Monte Carlo calculations, which include electric and magnetic fields in the x-ray tube as well as Joule heating, surface cooling, and thermal conduction in the cathode. The experimental result sand the result form the Monte Carlo calculations are presented.
