Seeing beneath the surface

X-ray tomography gives subsurface view of accelerator cavities

by Leah Hesla

Accelerator cavities have their faults, and some pits and cracks hide deep in the walls or in out-of-the-way places where they aren’t easily found. Accelerator researchers help improve flawed cavities by taking their fault-finding missions beneath the cavity surface with X-ray computed tomography.
