Noise Testing aka Singing to the Cryostat

Yesterday was a quiet day with many people spending much of the day looking at noise. Brad and Enzo arrived in the afternoon to join the excitement.

Some of the detectors are too sensitive to vibrations (microphonics), and a noisy fan in the star camera exacerbated the problem. The end result is that the cryostat is being warmed up to diagnose (and fix!) the problem.

The late night crew discovered that the detectors respond to music.
