Author(s)
William C. Thomas
This report is a supplement to the paper published as “Transient Thermal Response of an Extended Temperature Range 500-mm diameter Guarded Hot-plate Apparatus” by Thomas and Zarr (2018) [1], hereafter referred to as the “paper.” The paper emphasizes the

EUVL dosimetry at NIST

March 13, 2009
Author(s)
Charles S. Tarrio, Steven E. Grantham, Marc J. Cangemi, Robert E. Vest, Thomas B. Lucatorto, Noreen Harned
As part of its role in providing radiometric standards in support of industry, NIST has been active in advancing extreme ultraviolet dosimetry on various fronts. Recently, we undertook a major effort in accurately measuring the sensitivity of three extreme

Radial polarization imaging of entangled biphoton state

June 11, 2025

Thermal Conductivity of Two Compositions of Yttria-Stabilized Zirconia

June 1, 1999
Author(s)
Andrew J. Slifka, Bernard J. Filla, Judith K. Stalick
The thermal conductivities of two different compositions of yttria-stabilized zirconia have been measured using an absolute, steady-state method. The measurements were made in a one-dised guarded-hot-plate apparatus from 130 C to 950 C. one material has a
