Automated measurement of cavity frequency and cavity tuning at CEBAF
We propose a method here which allows the measurement of the cavity resonance frequency in a frequency range up to {plus_minus}5 kHz from the operating frequency. This is achieved by phase modulation of the incident signal with noise to drive the cavity with a broad band spectrum. The cavity resonance frequency can then be determined from the response signal of the field probe, which has a narrow frequency spectrum due to the high loaded Q of the cavity of 6.6{times}10{sup 6}, corresponding to a cavity bandwidth of 125 Hz.
