Description
We use the Pound reflection locking method to tune the cavity. We input
a phase-modulated RF signal to the cavity through a directional coupler.
The RF signal reflected by the cavity is given to a lock in amplifier
using a Zero bias Schottky detector. The output of the lock in amplifier
gives a measure of how far the carrier is off the resonance. This output
is fed to an integrator and the signal can be used as a feedback signal
to tune the cavity using a servo control.
