Power Monitors and Alignment Monitors

  Power monitor for high power evacuated 31.75 mm waveguide.
Nominal coupling is - 80dB at 110 GHz.

The power monitors are bi-directional, allowing simultaneous measurement of power traveling in each direction in the high power waveguide.

Power Monitor Miter Bends with coated diamond mirrors are under development. The (gray) diamond is edge-cooled and transmits a sample of the entire field in the high power waveguide. An alignment monitor can be connected to the low power side of the mirror. This monitor is useful for optimizing aligment of the microwave beam from the matching optics unit into the corrugated waveguide.
