A TDMA Hybrid SQUID Multiplexer

Author(s)
Carl D. Reintsema, James A. Beall, W.Bertrand (Randy) Doriese, William Duncan, S. L. Ferreira, Gene C. Hilton, Kent D. Irwin, Dan Schmidt, Joel Ullom, Leila R. Vale, Yizi Xu
We have developed a multiplexed read-out for transition edge sensors based on a hybrid time- and frequency-domain basis set, similar to that used in time...

Materials Analysis with Cryogenic Sensors

Author(s)
Joel N. Ullom
Low temperature photon detectors are increasingly attractive tools for materials analysis. Their range of applications has broadened from early work on x-ray...

Current Status of the Quantum Metrology Triangle

Author(s)
Mark W. Keller
The quantum metrology triangle is a test of the consistency of three quantum electrical standards: the single-electron tunneling current standard, the Josephson...

256-Channel Magnetic Imaging System

Author(s)
Fabio C. da Silva, Sean Halloran, Anthony B. Kos, David P. Pappas
We present the design and fabrication of a magentoresistive imaging system capable of measuring 256 channels simultaneously along linear ranges of 4 mm and 13...

Demonstration of a Multiplexer of Dissipationless SQUIDs}

Author(s)
John Mates, Gene C. Hilton, Kent D. Irwin, Leila R. Vale, Konrad Lehnert
We report on the development of a microwave SQUID multiplexer for reading out arrays of low-temperature detectors. In this frequency-division multiplexer, each...

256-channel magnetic imaging system

Author(s)
Fabio C. Da Silva, Sean Halloran, Anthony B. Kos, David P. Pappas
We present the design and fabrication of a magnetoresistive imaging system capable of scanning 256 channels simultaneously along linear ranges of either 4 or 13...

Instability in Pipe Flow

Author(s)
David Cotrell, Geoffrey B. McFadden, W. E. Alley, B. J. Alder
An axisymmetric linear stability analysis is carried out for flow driven by an axial pressure gradient in a pipe with axisymmetric and axially-periodic radius...

A Weighted GCV Method for Lanczos Hybrid Regularization

Author(s)
Julianne Chung, James G. Nagy, Dianne M. O'Leary
Lanczos-hybrid regularization methods have been proposed as effective approaches for solving large-scale ill-posed inverse problems. Lanczos methods restrict...

Probing molecules in integrated solid-state silicon junctions

Author(s)
Wenyong Wang, Adina Scott, Nadine Gergel-Hackett, Christina Hacker, David Janes, Curt A. Richter
In this research work, we fabricate integrated Si-SAMs-metal devices using the ?soft? top metal deposition technique and probe their electronic properties with...

Reinvestigation of the Microwave Spectrum of 2-Methylmalonaldehyde

Author(s)
Vadim V. Ilyushin, E A. Alekseev, Y C. Chou, Y-C Hsu, Jon T. Hougen, Francis J. Lovas, L B. Picaux
The molecule 2-methylmalonaldehyde (2-MMA) exists in the gas phase as a six-membered hydrogen-bonded ring [HO-CH=C(CH3)-CH=O] and exhibits two large-amplitude...
