Abstract

Methods and means for reduced ng the overall diameter of an x-ray tube by recessing the vacuum pumping port stub within the ground plane of the x-ray tube without adversely affecting the electrostatic fields within the vacuum tube itself are provided. In one embodiment, x-ray tubes of smaller diameter, which can be used within the highly confined diameters typically found within the pressure housings of borehole tools are used.

Claims (1)

1. A method for reducing the overall diameter of an x-ray tube, said method comprising recessing a vacuum pumping port stub within a ground plane of the x-ray tube without adversely affecting any electrostatic fields within the vacuum tube itself.
