Extremely large xenon clusters with sizes exceeding the predictions of the Hagena scaling law by several orders of magnitude are shown to be produced in pulsed gas jets. The cluster sizes are determined using single-shot single-particle imaging experiments with short-wavelength light pulses from the free-electron laser in Hamburg (FLASH). Scanning the time… (More)
Issues Addressed: Improve inseason escapement indices of salmon in the lower Copper River, downstream of the Miles Lake sonar site. Figure 4. Transducer mount with (1) Simrad transducer, (2) tiltmeter, (3) float switch and (4) set screws for adjusting the vertical position and tilt angle of the transducer. Figure 5. Differentiation between salmon and… (More)
Der Beitrag stellt das Kommunikations-und Kooperationsformat Webi-nar mit Fokus auf dessen Einsatz im Rahmen von E-Learning-Szenarien vor. Auf Grundlage der Erfahrungen, die im Rahmen der Q2P-Webinar-Reihe entstanden sind, werden Handlungsempfehlungen für die Vorbereitung, Durchführung und Nachbereitung von Webinaren abgeleitet.
We studied the nanoplasma formation and explosion dynamics of single large xenon clusters in ultrashort, intense x-ray free-electron laser pulses via ion spectroscopy. The simultaneous measurement of single-shot diffraction images enabled a single-cluster analysis that is free from any averaging over the cluster size and laser intensity distributions. The… (More)
Issues Addressed: Improve inseason escapement indices of salmon in the lower Copper River, downstream of the Miles Lake sonar site. Figure 4. Catch efficiency of Flag Point Channel acoustics, as measured by the ratio of the Flag Point Channel Index to the Miles Lake Sonar count (index per 1,000 fish counted at Miles Lake; 3-day moving average). For 2004 and… (More)
Irradiation of nanoscale clusters and large molecules with intense laser pulses transforms them into highly-excited non- equilibrium states. The dynamics of intense laser-cluster interaction is encoded in electron kinetic energy spectra, which contain signatures of direct photoelectron emission as well as emission of thermalized nanoplasma electrons. In… (More)
