Description
The phase noise spectra of the superconducting cavities of the ISAC 2 cryomodule and
of the test cryostat were measured under various conditions. Analysis of the results
show that the major contributors to this phase noise are microphonics, including
those from the superconducting cavities, the cryomodule and the power amplifiers,
each of which can be identified with their unique signatures. The results also
show
the effectiveness of the phase stabilizing loop in suppressing these noise
components. These measurements have become a useful diagnostic tool to identified
the various noise sources and verify the effectiveness of their suppression.
