Publikováno v: Waterbirds. 30:138-151
From 1986-2005, Virginia supported between 6% and 13% of the federally threatened Atlantic Coast Piping Plover (Charadrius melodus) breeding population with an annual average of 111 nesting pairs (SD ± 25.0, range = 84-192 pairs). The statewide popu

Publikováno v: Fourth-Generation X-Ray Sources and Ultrafast X-Ray Detectors.
An ultra fast, sub-picosecond resolution streak camera has been recently developed at the LLNL. The camera is a versatile instrument with a wide operating wavelength range. The temporal resolution of up to 300 fs can be achieved, with routine operati

PLEIADES: a subpicosecond Thomson x-ray source for ultrafast materials probing
Autor: Hyunchae Cynn, W. J. Brown, D. R. Slaughter, Christopher P. J. Barty, S. Anderson, Andy McMahan, James Rosenzweig, John A. Moriarty, Rex Booth, Robert R. Cross, Todd Ditmire, Frederic V. Hartemann, Jaroslav Kuba, David Gibson, Choong-Shik Yoo, John K. Crane, Gregory P. Le Sage, Frederick H. Streitz, Aaron Tremaine, P. T. Springer, David N. Fittinghoff
Publikováno v: SPIE Proceedings.
The use of ultrafast laser pulses to generate very high brightness, ultrashort (10 -14 to 10 -12 s) pulses of x-rays is a topic of great interest to the x-ray user community. In principle, femtosecond-scale pump-probe experiments can be used to tempo
