Planar Dielectric Accelerator Structures at W-band

摘要

We describe the operating principles, design, fabrication, assembly, and bench-test of a miniature planar dielectric traveling-wave accelerator structure made from dielectric brazed to oxygen-free electronic grade (OFE) copper. This work focuses on alumina ceramic (AL995) and diamond as dielectrics. This two-port device is matched to WR10 at input and output, and designed for charged particle acceleration at 91.392 GHz (W-band).
