An operational 150 kV microfocus rod anode X-ray system for non-destructive testing
article
This paper describes an operational 150 kV microfocus rod anode X-ray system which has ultra-high radiographic resolution and a focal spot size of less than 0.1 mm. Radiographic sensitivities of better than 1% through 3 mm of steel have been reported with film focal distances of the order of 8 mm. Long rod anodes are now possible with lengths up to 1 m or more and with diameters as small as 9 mm using mini-magnetic lens technology. This permits panoramic inspections; the system has been successfully applied to steam generator and heat exchanger tube-to-tubesheet weldments and also has applications where high reliability requirements, such as in marine and aircraft jet engine inspection, indicate the use of an ultra-sensitive radiographic technique. © 1978.
