3D- X-Ray high Energy Testing of Large Objects with Specialized Manipulation Trajectories

  • High-energy radiography is traditionally used for the detection of defects in thick-walled, bulky components. It is also used for testing the integrity of components for civil and security-related applications, e.g. containers. The combination of high-energy sources with digital detector arrays or line cameras allows carrying out the tests either in a shorter time compared to film technique, or with higher contrast sensitivity. The high-energy X-ray laboratory "HEXYLab" at BAM is a joint laboratory in which future users, manufacturers and scientists collaborate to initiate and develop joint development projects. The new universal manipulation system “HEXYTech” provides the engineering and technical base for meeting different requirements within HEXYLab. Different types of trajectories for tube, object and detector can be programmed with a total of 13 rotational and linear axes. In particular, large objects with complex geometries can be examined.

The new universal manipulation system “HEXYTech” provides the engineering and technical base for meeting different requirements within HEXYLab. Different types of trajectories for tube, object and detector can be programmed with a total of 13 rotational and linear axes. In particular, large objects with complex geometries can be examined. Measurements can be acquired as 2D images via standard radiography as well as 3D volumes from laminography or computed tomography reconstructions. The general rules for the application of high-energy radiography with digital detectors (imaging plates, digital detector arrays) were determined within the framework of the European project "HEDRad" (High Energy Digital Radiography) and added to the standard DIN EN ISO 17636-2. The paper gives an overview of the test technique and introduces several applications on the basis of experiments and reconstructed 3D- images.zeige mehrzeige weniger
