An absolute cavity pyrgeometer to measure the absolute outdoor longwave irradiance with traceability to International System of Units, SI

March 1, 2012
Author(s)
Ibrahim Reda, Jinan Zeng, Jonathan Scheuch, Leonard Hanssen, Daryl Myers, Boris Wilthan, Tom Stoffel
This article describes a method of measuring the absolute outdoor longwave irradiance using an absolute cavity pyrgeometer (ACP). The ACP consists ofa domeless thermopile pyrgeometer, gold- plated concentrator, temperature controller, and data acquisition

Extension of the resonance line series of Mg III

C M. Brown, Alexander Kramida, Uri Feldman, Joseph Reader
Spectra of Mg emitted by a Penning discharge were recorded in the extreme ultraviolet (EUV) on a 10.7-m grazing-incidence spectrograph with phosphor image plates. The spectra provided nine new lines of Mg III between 156 and 166 Å and allowed us to improve

Thermal-hydraulic Assessment of the Proposed NIST Neutron Source Design

October 6, 2023
Author(s)
Anil Gurgen, Abdullah Weiss, Joy Shen
To replace the ageing reactor at the NIST Center for Neutron Research, a new reactor design is proposed, namely the NIST Neutron Source or NNS. The NNS will contain a light-water moderated and cooled core that would serve as a neutron source for a state-of
