Lens Absorber Coupled MKIDs for Far Infrared Imaging Spectroscopy

Dabironezare, Shahab Oddin (author), van Berkel, Sven (author), Echternach, Pierre M. (author), Day, Peter K. (author), Bradford, Charles M. (author), Baselmans, J.J.A. (author)

Future generation of astronomical imaging spectrometers are targeting the far infrared wavelengths to close the THz astronomy gap. Similar to lens antenna coupled Microwave Kinetic Inductance Detectors (MKIDs), lens absorber coupled MKIDs are a candidate for highly sensitive large format detector arrays. However, the latter is more robust to...

Photon shot noise limited detection of terahertz radiation using a quantum capacitance detector

Echternach, P.M. (author), Stone, K.J. (author), Bradford, C.M. (author), Day, P.K. (author), Wilson, D.W. (author), Megerian, K.G. (author), Llombart Juan, N. (author), Bueno, J. (author)

We observed a sweep rate dependence of the quantum capacitance in a single Cooper-Pair box used as the readout of a Quantum Capacitance Detector. A model was developed that fits the data over five orders of magnitude in sweep rate and optical signal power and provides a natural calibration of the absorbed power. We are thereby able to measure...

Operation of a titanium nitride superconducting microresonator detector in the nonlinear regime

Swenson, L.J. (author), Day, P.K. (author), Eom, B.H. (author), Leduc, H.G. (author), Llombart, N. (author), McKenney, C.M. (author), Noroozian, O. (author), Zmuidzinas, J. (author)

If driven sufficiently strongly, superconducting microresonators exhibit nonlinear behavior including response bifurcation. This behavior can arise from a variety of physical mechanisms including heating effects, grain boundaries or weak links, vortex penetration, or through the intrinsic nonlinearity of the kinetic inductance. Although...

Equivalence Ratio Effects in Turbulent Premixed Methane-Air Flames

Day, M.S. (author), Bell, J.B. (author), Grcar, J.F. (author), Lijewski, M.J. (author)

Turbulent methane flames exhibit a change in Markstein number as the equivalence ratio changes. In this paper, we demonstrate how these changes in Markstein number are related to shifts in the chemistry and transport. We focus on the analysis of simulations of two-dimensional premixed turbulent methane flames at equivalence ratios 0.55 and 1.00...
