1. Characterization of the Optical Properties of an Infrared Blocked Impurity Band Detector
Published: 8/20/2011
Authors: Solomon I Woods, Simon Grant Kaplan, Timothy M. Jung, Adriaan C. Carter
Abstract: Si:As blocked impurity band detectors have been partially deprocessed and measured by Fourier transform spectroscopy to determine their transmittance and reflectance at cryogenic temperatures over the wavelength range 2 µm to 40 µm. The effective pr ...

2. Cryogenic Fourier Transform Infrared Spectrometer from 4 to 20 Micrometers
Published: 8/20/2010
Authors: Simon Grant Kaplan, Solomon I Woods, Timothy M. Jung, Adriaan C. Carter
Abstract: We describe the design and performance of a cryogenic Fourier transform spectrometer (Cryo-FTS) operating at a temperature of approximately 15 K. The instrument is based on a porch-swing scanning mirror design with active alignment stabilization usi ...

3. Demonstration of a Meissner-Effect Transition Edge Sensor
Published: 7/26/2010
Authors: Solomon I Woods, Stephen M. Carr, Timothy M. Jung, Adriaan C. Carter, Raju Vsnu Datla
Abstract: We have built and tested a transition edge sensor which monitors temperature change by measuring magnetic flux expulsion from a superconducting element. Flux change is sensed by a dc SQUID coupled to the element using a flux transformer in a gradiom ...

4. Calibration of Ultra-Low Infrared Power at NIST
Published: 7/20/2010
Authors: Solomon I Woods, Stephen M. Carr, Adriaan C. Carter, Timothy M. Jung, Simon Grant Kaplan, Raju Vsnu Datla
Abstract: The Low Background Infrared (LBIR) facility has developed and tested the components of a new detector for calibration of infrared powers down to 1 pW, with 0.1% uncertainty. Calibration of such low powers could be valuable for the quantitative study ...

5. Cryogenic Fourier transform spectrometer for infrared spectral calibrations from 4 to 20 micrometers
Published: 5/20/2010
Authors: Solomon I Woods, Simon Grant Kaplan, Timothy Michael Jung, Adriaan Carl Linus Carter, Raju Vsnu Datla
Abstract: We present initial performance data from a cryogenic Fourier transform spectrometer (Cryo-FTS) designed for low-background spectral infrared calibrations. The Cryo-FTS operates at a temperature of approximately 15 K and has been integrated into an in ...

6. Infrared Transfer Radiometer for Broadband and Spectral Calibration of Space Chambers
Published: 4/23/2010
Authors: Timothy M. Jung, Adriaan C. Carter, Solomon I Woods, Simon Grant Kaplan, Raju Vsnu Datla
Abstract: The Low-Background Infrared (LBIR) facility at NIST has recently completed construction of an infrared transfer radiometer with an integrated cryogenic Fourier transform spectrometer (Cryo-FTS). This mobile system can be deployed to customer sites f ...

7. Absolute Cryogenic Radiometer and Solid State Trap Detectors for IR Power Scales Down to 1 pW with 0.1% Uncertainty
Published: 6/2/2009
Authors: Adriaan Carl Linus Carter, Solomon I Woods, Stephen Carr, Timothy Michael Jung, Raju Vsnu Datla
Abstract: Commercially available Absolute Cryogenic Radiometers (ACRs) have combined uncertainties that grow rapidly above 1% at power levels below 10 nW. There are solid state detectors, however, used in sensors and radiometers that cannot be calibrated at l ...

8. PicoWatt Infrared Power Measurement using an Absolute Cryogenic Radiometer
Published: 5/7/2009
Authors: Stephen Carr, Solomon I Woods, Timothy Michael Jung, Adriaan Carl Linus Carter, Raju Vsnu Datla
Abstract: We report on initial measurements of the low-temperature thermal properties of a device that is similar to the experimental apparatus used for absolute cryogenic radiometry (ACR) within the Low Background Infrared Radiometry (LBIR) facility at NIST. ...

9. Infrared Absolute Calibrations Down to 10 fW in Low-Temperature Environments at NIST
Published: 7/22/2008
Authors: Adriaan Carl Linus Carter, Raju Vsnu Datla, Timothy Jung, Solomon Woods
Abstract: The Low Background Infrared (LBIR) facility at the National Institute of Standards and Technology (NIST) is responsible for absolute IR radiometric calibrations (SI traceable) in low-background temperature (below 80 K) environments. IR radiometric te ...
