CTF3 Cavity Pick-up to Waveguide Spacing

Cross Coupling

The separation between the pick-up in port number 2 and the wall of the waveguide was varied. The curve for separation of 0.2mm looks anomalous. This may be because the cavity was dismantled and reconstructed between this measurement and all the others.


Reflection and Transmission

This time, the separation between all pick-ups and the waveguide walls were varied simultaneously.


The loaded Q was measured at each separation. To this, a quadratic curve was fitted. The maxima of these curves are at Q=325.8 for S13 and 342.7 for S24. Are these the internal Q-values?
