Background Rates in Several Hard X-Ray Photon Counting Pixel Array Detectors
Alfred Q. R. Baron, Daisuke Ishikawa
Background rates in several pixel array detectors are investigated with an eye toward using them with hard, >6 keV, x-rays in very low-rate experiments - e.g. at signal rates <0.1/…
Novel Feature of Liquid Dynamics via Improvements in meV-Resolution Inelastic X-Ray Scattering
Alfred Q. R. Baron, Daisuke Ishikawa
We describe how improvements in methodology and instrumentation for meV-resolved inelastic x-ray scattering (IXS), coupled with a fresh examination of older theory, allow identific…
Experimental Observation of Mesoscopic Fluctuations to Identify Origin of Thermodynamic Anomalies of Ambient Liquid Water
Yukio Kajihara, Masanori Inui, Kazuhiro Matsuda +3
We report a new experimental approach for observing mesoscopic fluctuations underlying the thermodynamic anomalies of ambient liquid water. In this approach, two sound velocity mea…
Interaction of Acoustic and Quasi-Elastic Modes in Liquid Water on Nanometer Length Scales
Daisuke Ishikawa, Alfred Q. R. Baron
We investigate the presence of an acoustic-quasi-elastic interaction contribution in the IXS spectra of liquid water at 301K using inelastic x-ray scattering with sub-meV energy re…
Universal two-component dynamics in supercritical fluids
Peihao Sun, J. B. Hastings, Daisuke Ishikawa +2
Despite the technological importance of supercritical fluids, controversy remains about the details of their microscopic dynamics. In this work, we study four supercritical fluid s…
Density deficit of the Earth's core revealed by a multi-megabar primary pressure scale
Daijo Ikuta, Eiji Ohtani, Hiroshi Fukui +4
An accurate pressure scale is a fundamental requirement to understand planetary interiors. Here, we establish a primary pressure scale extending to the multi-megabar pressures of t…
