  1. Gallium-based Ultraviolet Nanoplasmonics

    Yang, Yang2013

    … metals: Au and Ag. Plasmonic applications in ultraviolet (UV) are of great interest because Raman scattering sections are larger and do not overlap fluorescence spectra. UV plasmonics also benefit from high spatial resolution and low penetration depth. However, an appropriate UV plasmonic …

  4. Extreme ultraviolet probing of laser ablation

    Hobbs, LaurenUniversity of York2011

    This thesis details the use of extreme ultraviolet (EUV) sources in probing laser ablation and material opacity. The radiation hydrodynamic codes POLLUX and h2d are used to study the Rayleigh-Taylor instability in a regime relevant to inertial fusion energy and, in support of experimental effort, …

  7. Transient extreme ultraviolet spectroscopy of semiconductors

    Verkamp, Max AndrewUniversity of Illinois at Urbana-Champaign2019

    Transient extreme ultraviolet (XUV) spectroscopy is used to investigate ultrafast photophysics in lead iodide (PbI2) and methylammonium lead iodide perovskite (MAPbI3). Sub-30 fs pulses of XUV light are produced to use as a probe in a tabletop instrument using high-harmonic generation. PbI2 and …

    Elliott, Grant (Grant Andrew)Massachusetts Institute of Technology2006

    We demonstrate the use of a focused ultraviolet laser as a track calibration source in drift chambers, and specifically in a small time projection chamber (TPC). Drift chambers such as TPCs reconstruct the trajectories of charged particles by amplifying and collecting electrons produced by …
