abstract = "Interferometric gravitational wave observatories recently launched
a new field of gravitational wave astronomy with the first
detections of gravitational waves in 2015. The number and quality
of these detections is limited in part by thermally induced
vibrations in the mirrors, which show up as noise in these
interferometers. One way to reduce this thermally induced noise is
to use low temperature mirrors made of high purity
single-crystalline silicon. However, these low temperatures must
be achieved without increasing the mechanical vibration of the
mirror surface or the vibration of any surface within close
proximity to the mirrors. The vibration of either surface can
impose a noise inducing phase shift on the light within the
interferometer or physically push the mirror through oscillating
radiation pressure. This paper proposes a system for the Laser
Interferometric Gravitational-wave Observatory (LIGO) to achieve
the dual goals of low temperature and low vibration to reduce the
thermally induced noise in silicon mirrors. Experimental results
are obtained at Stanford University to prove that these dual goals
can be realized simultaneously.",
