SUMMARY:Searching for Dark Matter with Superconducting Quantum Interfe
 rence Devices\, Physics Department Colloquium\, Kent Irwin\, Stanford/
 SLAC
DESCRIPTION:For several decades\, Superconducting Quantum Interference
  Devices (SQUIDs) have played an important role in searching for the m
 ysterious dark matter that makes up about 85% of the matter in the uni
 verse. SQUIDs have been used in both direct searches for dark matter a
 nd in CMB experiments used to constrain the dark matter annihilation c
 ross section. I describe the historical role that SQUIDs have played i
 n direct-detection WIMP experiments\, CMB dark-matter detection experi
 ments\, and more recently in searches for pseudoscalar axion dark matt
 er. I then describe an experiment that we are now constructing to sear
 ch for ultralight vector-boson dark matter ("hidden photons") with a l
 umped-element resonator\, essentially a radio for dark matter detectio
 n. In its ultimate implementation\, this experimental campaign will ul
 timately exclude or detect hidden-photon dark matter over six orders o
 f magnitude in coupling - down to mixing angles of 10^-17 - and nine o
 rders of magnitude in mass (from 100 Hz to 700 GHz). I describe the de
 sign of this experiment and challenges to achieving its ultimate scien
 ce reach.
