  • Time-resolving Electron Energy analyzer measurements of intense relativistic beam transport
    1990 Plasma Science IEEE Conference Record - Abstracts, 1990
    Co-Authors: D.j. Weidman, M.j. Rhee, R.f. Schneider
    Abstract:

    Summary form only given. A time-resolving Electron Energy (TREE) analyzer has been used to measure a 2-MeV, 20-ns intense relativistic Electron beam. Time-resolved Energy measurements have been taken immediately downstream of the diode and after a transport region. This provides direct experimental measurement of the effect of the transport region on beam Energy and pulse shape. The TREE analyzer consists of a compact magnetic Electron Energy analyzer, a fast detector, and a streak camera. The characteristics of the analyzer are discussed

  • Time-Resolved Electron Energy Analyzer
    Japanese Journal of Applied Physics, 1992
    Co-Authors: Katsumi Hirano, Kouji Asami, Makoto Shindo, Toshikazu Yamamoto
    Abstract:

    An Electron Energy analyzer is designed for time-resolved measurement of pulsed energetic Electron beams whose Energy is in the range from 200 keV to several MeV, and successfully used to obtain Energy distribution of the Electron beam generated by a plasma focus device. The beam detection system is based on the Cerenkov effect. The radiation is detected by six photomultipliers through optical fibers mounted at different angles which depend on the Electron Energy. For the optical medium, Lucite is employed. Energy resolution of the detector is presented as a function of the Electron Energy. The signal ratio of the Cerenkov radiation to the scintillation by X-rays, which is always produced with a high-temperature plasma, is evaluated experimentally.

  • computation of Electron Energy loss spectra by an iterative method
    Nuclear Instruments & Methods in Physics Research Section B-beam Interactions With Materials and Atoms, 2015
    Co-Authors: Daniel Sanchezportal, Mathias P Ljungberg, Peter Koval, Dietrich Foerster
    Abstract:

    A method is presented to compute the dielectric function for extended systems using linear response time-dependent density functional theory. Localized basis functions with finite support are used to expand both eigenstates and response functions. The Electron-Energy loss function is directly obtained by an iterative Krylov-subspace method. We apply our method to graphene and silicon and compare it to plane-wave based approaches. Finally, we compute Electron-Energy loss spectrum of C60 crystal to demonstrate the merits of the method for molecular crystals, where it will be most competitive.
