CT on an Electron GUN

1024 773 XRAY-LAB | Industrial X-ray analysis & 3D computed tomography (CT)

X-ray tomography has been established as a nondestructive
three-dimensional analysis tool, commercially
offered by industrial vendors. Typical applications cover
shape control and failure detection (voids, cracks) deep
inside of complicated bulk pieces like engine blocks,
bearings, turbine blades etc.. We evaluated the
applicability of the process for superconducting radio
frequency cavities, in particular a generic 1.3 GHz single
test cell cavity, the 1.4-cell 1.3 GHz bERLinPro electron
gun cavity and the 1.5 GHz VSR-1-cell-prototype cavity.
The gun cavity experienced severe shape modifications
during its tuning process and features a complicated
internal stiffening construction.
