Volumetric Performance Evaluation of a Laser Scanner Based on Geometric Error Model

Author(s)
Balasubramanian Muralikrishnan, Massimiliano M. Ferrucci, Daniel S. Sawyer, Grant Gerner, Vincent D. Lee, Christopher J. Blackburn, Steven D. Phillips, Yuri Yakovlev, Andrey Astrelin, Spike Milligan, John Palmateer
We discuss a geometric error model for those large volume laser scanners that have the laser source and a spinning prism mirror mounted on a platform that can...

Substitution of Ni for Fe in Superconducting Fe0.98Te0.5Se0.5 Depresses the Normal-State Conductivity but not the Magnetic Spectral Weight

Author(s)
Jinghui Wang, Ruidan Zhong, Shichao Li, Yuan Gan, Zhijun Xu, Cheng Zhang, T Ozaki, M. Matsuda, Yang Zhao, Qiang Li, Guangyong Xu, Genda Gu, J. M. Tranquada, R. J. Birgeneau, Jinsheng Wen
We have performed systematic resistivity and inelastic neutron scattering measurements on Fe 0.98-zNi zTe 0.5Se 0.5 samples to study the impact of Ni...

Optical Lattice Clocks

Author(s)
Andrew D. Ludlow, Christopher W. Oates
Here we introduce and give a basic description of optical lattice clocks. We also briefly describe recent advances in these atomic frequency standards, looking...

Atomic Clock with 1x10-18 Room-Temperature Blackbody Stark Uncertainty

Author(s)
Kyle P. Beloy, Nathan M. Hinkley, Nate B. Phillips, Jeffrey A. Sherman, Marco Schioppo, John H. Lehman, Ari D. Feldman, Leonard M. Hanssen, Christopher W. Oates, Andrew D. Ludlow
The Stark shift due to blackbody radiation (BBR) is a key factor limiting the performance of many atomic frequency standards, with the BBR environment inside...

Tailor-Made Polyamide Membranes for Water Desalination

Author(s)
Edwin P. Chan, Wansuk Chol, Joona Bang, Jong Suk Lee, Jung-Hyun Lee, Joung-Eun Gu
Independent control over the extrinsic and intrinsic properties of the polyamide selective layer is critical when designing water desalination reverse osmosis...
