The QCD axion is a leading dark matter candidate that emerges as part of the solution to strong CP problem in Standard Model. coupling photons most common experimental probe, but much parameter space remains unexplored. Model scales linearly with mass; therefore, highly-motivated region 0.4-120 neV, corresponding GUT-scale axion, particularly difficult reach. This paper presents design requirements for definitive search axions and reviews technological advances needed enable this program.
The next generation of cosmic microwave background (CMB) polarization experiments targeting the signatures inflation will require unprecedented sensitivities in addition to careful control systematics. With existing detector technologies approaching photon noise limit, improvements system must come from ever‐larger focal plane arrays millimeter‐wave detectors. We report on design and performance microfabricated planar orthomode transducer (OMT) coupled TES polarimeters silicon micromachined...
Aluminum lumped-element kinetic inductance detectors (LEKIDs) sensitive to millimeter-wave photons have been shown exhibit high quality factors, making them highly and multiplexable. The superconducting gap of aluminum limits LEKIDs photon frequencies above 100 GHz. Manganese-doped (Al-Mn) has a tunable critical temperature could therefore be an attractive material for below GHz if the internal factor remains sufficiently when manganese is added film. To investigate, we measured some key...
We present experimental measurements of SQUID-induced damping effects on strongly coupled, lumped-element resonators in the 500kHz–1 MHz frequency range. While dc SQUIDs are commonly used for sensitive readout electromagnetic signals such as axion dark matter searches, coupling a SQUID to resonant circuit modifies circuit's resonance frequency, quality factor, noise, and impedance. These parameters have direct impact science reach detectors, making it important understand contributions....
