    Advanced numerical studies of the neutralized drift compression of intense ion beam pulses by Adam B. Sefkow, Ronald C. Davidson

    Published 2007-10-01
    “…Longitudinal bunch compression of intense ion beams for warm dense matter and heavy ion fusion applications occurs by imposing an axial velocity tilt onto an ion beam across the acceleration gap of a linear induction accelerator, and subsequently allowing the beam to drift through plasma in order to neutralize its space-charge and current as the pulse compresses. …”

    Insight into <i>Emiliania huxleyi</i> coccospheres by focused ion beam sectioning by R. Hoffmann, C. Kirchlechner, G. Langer, A. S. Wochnik, E. Griesshaber, W. W. Schmahl, C. Scheu

    Published 2015-02-01
    “…Coccospheres of a cultured <i>Emiliania huxleyi</i> clone were sampled in the exponential growth phase and sectioned using a focused ion beam microscope. An average of 69 sections and the corresponding secondary electron micrographs per coccosphere provided detailed information on coccosphere architecture. …”
