Calibration for Astrophysics using an Artificial star with NIST-traceable Distribution of Luminous Energy (CANDLE) Instrument Development

August 23, 2024
Author(s)
Joseph P. Rice, Brian Alberding, Susana Deustua, Thinh Bui, Eric Shirley, Keshet Shavit, Eliad Peretz, Daniel Kuesters, Greg Aldering, Dmitry Vorobiev, Jonathan Papa, Justin Albert, Ralph Bohlin, Benjamin Rose, Piotr Pachowicz, Peter Plavchan, Angella Tanner, John Mather, Jean Thomas Landry, Etienne Gauvin, Thomas Michaud=Bayens, Greg Kopp
The CANDLE Engineering Demonstration Unit (EDU) was selected by the 2022 APRA program to develop and demonstrate that we can reach the flux accuracy and range required for an artificial star. A critical issue in producing accurate and reliable flux

QUASAR-QUAsi-Stationary Absolute Radiance Mission

Eliad Peretz, Peter Plavchan, Piotr Pachowicz, Jamie Tayar, Gerard van Belle, Greg Aldering, Angelle Tanner, Justin Albert, Daniel Huber, Leonard Hanssen, Brian Alberding, Joseph P. Rice, Steven West, John Mather, Allison Youngblood, Tabetha Boyajian, Brian Stalder, Jonathan Gagne, Susana Deustua, Kayla Carmical, Andrew Lewis
This paper describes the scientific and developmental aspects behind the QUAsi-Stationary Absolute Radiance (QUASAR) mission study. The scientific motivation on which the mission is built is established, including the absolute flux calibration of standard

A pyroelectric detector-based method for low uncertainty spectral irradiance and radiance responsivity calibrations in the infrared using tunable lasers

April 4, 2022
Author(s)
Brian Alberding, John Woodward, Ping-Shine Shaw, Leonard Hanssen, Catherine Cooksey, Joseph P. Rice
The standard uncertainty of detector-based radiance and irradiance responsivity calibrations in the short-wave infrared (SWIR) traditionally has been limited to around 1 % or higher by the low spatial uniformity of detectors used to transfer the scale from

Contact and Non-Contact Measurement of Electronic Transport in Individual 2D SnS Colloidal Semiconductor Nanocrystals

September 24, 2018
Author(s)
Adam J. Biacchi, Son T. Le, Brian G. Alberding, Joseph A. Hagmann, Sujitra J. Pookpanratana, Edwin J. Heilweil, Curt A. Richter, Angela R. Hight Walker
Colloidal-based solution syntheses offer a scalable and cost-efficient means of producing 2D nanomaterials in high yield. While much progress has been made towards the controlled and tailorable synthesis of semiconductor nanocrystals in solution, it

Femtosecond Laser Eyewear Protection: Measurements and Precautions for Amplified High Power Applications

September 24, 2018
Author(s)
Christopher J. Stromberg, Sarah Wirick, Maximilian Riedel-Topper, Brian Alberding, Joshua A. Hadler, Edwin J. Heilweil
Ultrafast lasers have become increasingly important as research tools in laboratories and commercial enterprises suggesting laser safety, personal protection and awareness becomes ever more important. Laser safety eyewear are typically rated by their

Ultrafast Laser Eyewear Protection: Measurements and Precautions

September 25, 2017
Author(s)
Christopher J. Stromberg, Joshua A. Hadler, Brian Alberding, Edwin J. Heilweil
Ultrafast laser systems are becoming more widespread throughout the research and industrial communities yet eye protection for these high power, bright pulsed sources still require scrupulous characterization and testing before use. Femtosecond lasers

Elucidating the Structural and Electronic Properties of Solution-Synthesized 2D SnS Crystals

March 28, 2017
Author(s)
Adam J. Biacchi, Brian G. Alberding, Son T. Le, Joseph A. Hagmann, Sugata Chowdhury, Curt A. Richter, Edwin J. Heilweil, Angela R. Hight Walker
The vast majority of nanoscale 2D materials are synthesized by exfoliation or gas phase deposition techniques. Alternatively, bottom-up colloidal solution syntheses offer a scalable and cost-efficient means of producing 2D nanomaterials in high yield

Static and Time-Resolved Terahertz Measurements of Photoconductivity in Solution-Deposited Ruthenium Oxide Nanofilms

January 25, 2017
Author(s)
Brian Alberding, Paul A. Desario, Adam D. Dunkelberger, Debra R. Rolison, Jeffrey C. Owrutsky, Edwin J. Heilweil
Thin film Ruthenium Oxide (RuO2) is a promising alternative material as a conductive electrode in electronic applications because its rutile crystalline form is metallic and highly conductive. Herein, a previously established solution-deposition multi

Charge Carrier Dynamics and Mobility Determined by Time-Resolved Terahertz Spectroscopy on Films of Nano-to-Micrometer-Sized Colloidal Tin(II) Monosulfide

August 1, 2016
Author(s)
Brian Alberding, Adam Biacchi, Angela R. Hight Walker, Edwin J. Heilweil
Tin(II) monosulfide (SnS) is a semiconductor material with an intermediate band gap, high absorption coefficient is the visible range, and consists of earth abundant, non-toxic elements. For these reasons, SnS has generated much interest for incorporation

Transient Optical and Terahertz Spectroscopy of Nanoscale RuO2

August 1, 2016
Author(s)
Edwin J. Heilweil, Brian G. Alberding, Paul D. Cunningham, Joseph S. Melinger, Jeffrey C. Owrutsky, Adam D. Dunkelberger
Solution-deposited nanoscale films of RuO2, “nanoskins,” are effective transparent conductors because after calcining to 523 K they exhibit flat optical extinction across the visible and infrared combined with relatively high electrical conductivity. Upon
