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…
Structural changes across thermodynamic maxima in supercooled liquid tellurium: a water-like scenario
Peihao Sun, Giulio Monaco, Peter Zalden +10
Liquid polymorphism is an intriguing phenomenon which has been found in a few single-component systems, the most famous being water. By supercooling liquid Te to more than 130 K be…
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…
