Query: A Study of Cooling Time Reduction of Interferometric Cryogenic
  Gravitational Wave Detectors Using a High-Emissivity Coating   In interferometric cryogenic gravitational wave detectors, there are plans to
cool mirrors and their suspension systems (payloads) in order to reduce thermal
noise, that is, one of the fundamental noise sources. Because of the large
payload masses (several hundred kg in total) and their thermal isolation, a
cooling time of several months is required. Our calculation shows that a
high-emissivity coating (e.g. a diamond-like carbon (DLC) coating) can reduce
the cooling time effectively by enhancing radiation heat transfer. Here, we
have experimentally verified the effect of the DLC coating on the reduction of
the cooling time.
