Surface roughness in polycrystalline copper under cyclic thermal loading: FFT-based thermomechanical modelling with experimental verification for accelerator applications [Slides]
The copper chambers contain an electromagnetic field known as radiofrequency (RF) cavities. Accelerator cavities have superior surface finish with roughness, Ra, of about 0.05 to 0.1 µm. For reference, mirror finish is 0.8 μm.
