Measuring the electron neutrino mass with improved sensitivity: the HOLMES experiment
A. Giachero, B. Alpert, D. Becker +39
HOLMES is a new experiment aiming at directly measuring the neutrino mass with a sensitivity below 2 eV. HOLMES will perform a calorimetric measurement of the energy released in th…
Critical Temperature tuning of Ti/TiN multilayer films suitable for low temperature detectors
A. Giachero, P. Day, P. Falferi +8
We present our current progress on the design and test of Ti/TiN Multilayer for use in Kinetic Inductance Detectors (KIDs). Sensors based on sub-stoichiometric TiN film are commonl…
A Titanium Nitride Absorber for Controlling Optical Crosstalk in Horn-Coupled Aluminum LEKID Arrays for Millimeter Wavelengths
H. McCarrick, D. Flanigan, G. Jones +15
We discuss the design and measured performance of a titanium nitride (TiN) mesh absorber we are developing for controlling optical crosstalk in horn-coupled lumped-element kinetic…
High quality factor manganese-doped aluminum lumped-element kinetic inductance detectors sensitive to frequencies below 100 GHz
G. Jones, B. R. Johnson, M. H. Abitbol +12
Aluminum lumped-element kinetic inductance detectors (LEKIDs) sensitive to millimeter-wave photons have been shown to exhibit high quality factors, making them highly sensitive and…
Design and performance of dual-polarization lumped-element kinetic inductance detectors for millimeter-wave polarimetry
H. McCarrick, G. Jones, B. R. Johnson +11
Lumped-element kinetic inductance detectors (LEKIDs) are an attractive technology for millimeter-wave observations that require large arrays of extremely low-noise detectors. We de…
Fermi-surface topology and the effects of intrinsic disorder in a class of charge-transfer salts containing magnetic ions, β''-(BEDT-TTF)_4[(H_3O)M(C_2O_4)_3]Y

We report high-field magnetotransport measurements on β''-(BEDT-TTF)_4[(H_3O)M(C_2O_4)_3]Y, where M=Ga, Cr and Fe and Y=C_5H_5N. We observe similar Shubnikov-de Haas oscillations…
Status of SuperSpec: A Broadband, On-Chip Millimeter-Wave Spectrometer
S. Hailey-Dunsheath, E. Shirokoff, P. S. Barry +16
SuperSpec is a novel on-chip spectrometer we are developing for multi-object, moderate resolution (R = 100 - 500), large bandwidth (~1.65:1) submillimeter and millimeter survey spe…
Development of Multi-Chroic MKIDs for Next-Generation CMB Polarization Studies
B. R. Johnson, D. Flanigan, M. H. Abitbol +17
We report on the status of an ongoing effort to develop arrays of horn-coupled, polarization-sensitive microwave kinetic inductance detectors (MKIDs) that are each sensitive to two…
The Quantum Capacitance Detector: A concept for a pair-breaking radiation detector based on the single Cooper-pair box
M. D. Shaw, J. Bueno, P. Day +2
We present a proposed design for a pair-breaking photodetector for far-infrared and sub-millimeter radiation. Antenna-coupled radiation generates quasiparticles in a superconductin…
Antenna-coupled TES bolometers for the Keck Array, Spider, and Polar-1
R. O'Brient, P. A. R. Ade, Z. Ahmed +50
Between the BICEP2 and Keck Array experiments, we have deployed over 1500 dual polarized antenna coupled bolometers to map the Cosmic Microwave Background's polarization. We have b…
