    Ultrafast Imaging of Laser Driven Shock Waves using Betatron X-rays from a Laser Wakefield Accelerator 

    Wood, J. C.; Chapman, D. J.; Poder, K.; Lopes, N. C.; Rutherford, M. E.; Whites, T. G.; Albert, F.; Behm, K. T.; Booth, N.; Bryant, J. S. J.; Foster, P. S.; Glanzer, S.; Hill, E.; Krushelnick, K.; Najmudin, Z.; Pollock, B. B.; Rose, S.; Schumaker, W.; Scott, R. H. H.; Sherlock, M.; Thomas, A. G. R.; Zhao, Z.; Eakins, D. E.; Mangles, S. P. D. (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 

    McCurdy, C. W.; Rescigno, T. N.; Trevisan, C. S.; Lucchese, R. R.; Gaire, B.; Menssen, A.; Schoeffler, M. S.; Gatton, A. S.; Neff, J.; Stammer, P. M.; Rist, J.; Eckart, S.; Berry, B.; Severt, T.; Sartor, J.; Moradmand, A.; Jahnke, Till; Landers, A. L.; Williams, J. B.; Ben-Itzhak, I.; Doerner, Reinhard; Belkacem, A.; Weber, Th (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 

    Nagayama, Taisuke; Mancini, Roberto C.; Mayes, Daniel C.; Tommasini, R.; Florido, R. (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 

    Mori, Yoshitaka; Sekine, Takashi; Komeda, Osamu; Nishimura, Yasuhiko; Sunahara, Atsushi; Miura, Eisuke; Nakayama, Suisei; Hanayama, Ryohei; Ishii, Katsuhiro; Sato, Nakahiro; Kurita, Takashi; Kawashima, Toshiyuki; Kan, Hirofumi; Nakamura, Naoki; Kondo, Takuya; Fujine, Manabu; Azuma, Hirozumi; Hioki, Tatsumi; Kakeno, Mitsutaka; Kajino, Tsutomu; Motohiro, Tomoyoshi; Sentoku, Yasuhiko; Kitagawa, Yoneyoshi (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 

    Murata, Shunichi; Nakajima, Takayuki; Safronova, Marianna S.; Safronova, Ulyana I.; Nakamura, Nobuyuki (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 

    Ranjit, Gambhir; Cunningham, Mark S.; Casey, Kirsten; Geraci, Andrew A. (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 ...
