Shannon Duff (Fed)

Shannon Duff is an Electronics Engineer in the Quantum Sensors Group within the Quantum Electromagnetics Division of the Physical Measurement Laboratory at NIST in Boulder, CO.  Upon joining the Quantum Sensors Group in 2015, she began leading the development of micro-fabrication processes for densely packed, large-format arrays of superconducting transition edge sensor (TES) polarimeters for making precise measurements of the Cosmic Microwave Background (CMB).  This development has enabled many successful cosmological observations with NIST-fabricated detectors.  Shannon continues to lead millimeter-wave and far-infrared detector process development, while working toward realizing next-generation superconducting sensors for a variety of applications.

RESEARCH INTERESTS

  • Superconducting sensor arrays for Cosmic Microwave Background observations 
  • Development of ultra-low noise transition edge sensors for far infrared astrophysics
  • Micro-fabrication process development for next-generation superconducting readout and detectors (e.g., NIS-TES and SQUIDs on 150 mm wafers)
