Target Monitoring and Plasma Diagnosis using 2 omega probe beam for CANDY
(2016)We have developed the shadowgraph and interferometer with second-harmonic of heating pulses laser to observe target and plasma in highly-repetitive fusion reaction experiments. In the deuterated polystyrene ((C8D8) n double ... -

The concept of transport capacity in geomorphology
(2015)The notion of sediment-transport capacity has been engrained in geomorphological and related literature for over 50 years, although its earliest roots date back explicitly to Gilbert in fluvial geomorphology in the 1870s ... -

The Two-Column Aerosol Project: Phase I-Overview and impact of elevated aerosol layers on aerosol optical depth
(2016)The Two-Column Aerosol Project (TCAP), conducted from June 2012 through June 2013, was a unique study designed to provide a comprehensive data set that can be used to investigate a number of important climate science ... -

Theoretical study of the g factor and lifetime of the 6s6 p P-3(0) state of mercury
(2017)We calculate the g factor of the 6s6p (3) P-0 state of 199 and 201 mercury isotopes using a relativistic high-precision all-order method that combines the configuration interaction and the coupled-cluster approaches. Our ... -

Towards a Mg Lattice Clock: Observation of the S-1(0)-P-3(0) Transition and Determination of the Magic Wavelength
(2015)We optically excite the electronic state 3s3p P-3(0) in Mg-24 atoms, laser cooled and trapped in a magic-wavelength lattice. An applied magnetic field enhances the coupling of the light to the otherwise strictly forbidden ... -

Tracing intermolecular Coulombic decay of carbon-dioxide dimers and oxygen dimers after valence photoionization
(2019)We have conducted an experimental study on the photo double ionization (PDI) of carbon-dioxide dimers at photon energies of 37 and 55 eV and oxygen dimers at photon energies of 38, 41.5, and 46 eV, while focusing on the ... -

Transitions between the 4f-core-excited states in Ir16+, Ir17+, and Ir18+ ions for clock applications
(2015)Iridium ions near 4f - 5s level crossings are the leading candidates for a new type of atomic clocks with a high projected accuracy and a very high sensitivity to the temporal variation of the fine structure constant a. ... -

Transport and spatial energy deposition of relativistic electrons in copper-doped fast ignition plasmas
(2017)Fast electron transport and spatial energy deposition are investigated in integrated cone-guided Fast Ignition experiments by measuring fast electron induced copper K-shell emission using a copper tracer added to deuterated ... -

Two-color monochromatic x-ray imaging with a single short-pulse laser
(2017)Simultaneous monochromatic crystal imaging at 4.5 and 8.0 keV with x-rays produced by a single short-pulse laser is presented. A layered target consisting of thin foils of titanium and copper glued together is irradiated ... -

Two-Particle Interference of Electron Pairs on a Molecular Level
(2016)We investigate the photodouble ionization of H-2 molecules with 400 eV photons. We find that the emitted electrons do not show any sign of two-center interference fringes in their angular emission distributions if considered ... -

Ultrafast Imaging of Laser Driven Shock Waves using Betatron X-rays from a Laser Wakefield Accelerator
(2018)Betatron radiation from laser wakefield accelerators is an ultrashort pulsed source of hard, synchrotron-like x-ray radiation. It emanates from a centimetre scale plasma accelerator producing GeV level electron beams. In ... -

Unambiguous observation of F-atom core-hole localization in CF4 through body-frame photoelectron angular distributions
(2017)A dramatic symmetry breaking in K-shell photoionization of the CF4 molecule in which a core-hole vacancy is created in one of four equivalent fluorine atoms is displayed in the molecular frame angular distribution of the ... -

Understanding reliability and some limitations of the images and spectra reconstructed from a multi-monochromatic x-ray imager
(2015)Temperature and density asymmetry diagnosis is critical to advance inertial confinement fusion (ICF) science. A multi-monochromatic x-ray imager (MMI) is an attractive diagnostic for this purpose. The MMI records the ... -

Upgrade of repetitive fast-heating fusion driver HAMA to implode a shell target by using diode pumped solid state laser
(2016)The HAMA is 1-Hz fast heating fusion driver pumped by a 10 J second-harmonic of diode-pumped Nd:glass laser: KURE-1. We have upgraded HAMA to realize an implosion of spherical shell target by using a remaining fundamental ... -

Visible transitions in Ag-like and Cd-like lanthanide ions
(2017)We present visible spectra of Ag-like (4d(10)4f) and Cd-like (4d(10)4f(2)) ions of Ho (atomic number Z = 67), Er (68), and Tm (69) observed with a compact electron beam ion trap. For Ag-like ions, prominent emission ... -

Zeptonewton force sensing with nanospheres in an optical lattice
(2016)Optically trapped nanospheres in high vacuum experience little friction and hence are promising for ultrasensitive force detection. Here we demonstrate measurement times exceeding 10(5) s and zeptonewton force sensitivity ...
