    Spectrum of transition radiation from hot electrons generated in ultra-intense laser plasma interaction (2002)

    Notes: The spectrum of transition radiation from a relativistic hot electron beam with the Boltzmann energy distribution is theoretically studied. The spectrum of transition radiation is separated into two parts: one is the incoherent spectrum, the other is the coherent spectrum. The results show that the temperature and total number of hot electrons can be obtained from the incoherent spectrum, and that the perturbation wave number in an electron bunch can be deduced from the coherent spectrum, from which the dominant heating process can be studied. © 2002 American Institute of Physics.

    Instantaneous spherical electron focusing in a Penning trap (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: In the electron beam Penning trap, electron focusing at the trap center by means of injecting low-canonical-angular-momentum electrons has been identified. It is found that the focusing occurs instantaneously under the condition that the injection current is larger than a threshold and the effective electric potential well is spherical. A self-consistent model is proposed to describe the setup process of the dense core. According to the model the instantaneous core density is evaluated to be about one order greater than the corresponding Brillouin density. © 2000 American Institute of Physics.

    Harmonic emission with cyclotron satellite structure due to strong magnetic fields produced by ultra-intense laser–plasma interaction (2002)

    Notes: Under the action of an intense laser and strong magnetic field, an electron undergoes oscillation at a cyclotron frequency, as well as the frequency of the incident wave. The coupling between the drift cyclotron and figure-8 motions can generate sidebands in the vicinity of all harmonics. The frequency separation between the sidebands could be used to infer the magnitude of the self-generated magnetic field.© 2002 American Institute of Physics.

    Effects of non-Maxwellian (super-Gaussian) electron velocity distribution on the spectrum of Thomson scattering (1997)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 4 (1997), S. 2736-2740 
    Details
    ISSN: 1089-7674

    Topics: Physics
    Notes: The dynamic form factor for Thomson scattering with a non-Maxwellian (super-Gaussian) electron velocity distribution is analytically and numerically studied for the first time. Both the ion and electron features of the spectra for α〉1 are found to be affected strongly. For the ion feature, the use of the usual theoretical spectra with the assumption of a Maxwellian distribution for fitting the measured Thomson scattering spectra may have resulted in some errors in calculating the plasma parameters in high-Z plasmas irradiated with high intensity light. However, it is impossible to use the ion feature of the measured spectra alone to deduce the form of the electron distribution. For the electron feature, the spectral shape (in particular the peak amplitude) changes sensitively with the distribution index. It would be possible to detect the super-Gaussian distribution by simultaneously measuring the ion and electron features of the spectra. © 1997 American Institute of Physics.

    Effects of super-Gaussian electron velocity distributions on the ion feature of Thomson scattering off two-ion plasmas (2002)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 9 (2002), S. 1073-1078

    Topics: Physics
    Notes: The influence of super-Gaussian velocity distributions on the ion feature of Thomson scattering off two-ion plasmas is studied. The analytical solution to the dispersion equation shows that although both the frequencies of the two (fast and slow) ion-acoustic waves increase with the index of the super-Gaussian, the slow wave is more weakly dependent on the index due to the screening of the light ions. In the case that plasma can sustain two lightly damped ion-acoustic waves, the inferred plasma parameters such as electron temperature and plasma temperature ratio may suffer some errors without consideration of super-Gaussian electron velocity distributions. Since the relative intensity between the resonant peaks of the fast and slow waves is sensitive to the super-Gaussian index, the super-Gaussian velocity distributions may be measurable with Thomson scattering off laser-heated two species ion plasmas. © 2002 American Institute of Physics.

    Notes: Detailed measurements of gold plasmas produced with 0.351 μm laser light are reported. The temporal and spatial variations of Z¯Te are obtained in the case that pump intensities are 6.5×1013 and 1.4×1014 W/cm2. The experimental results are qualitatively consistent with two nonlocalized absorption models. © 2001 American Institute of Physics.

    Modification of electron transport due to dynamic screening of the Coulomb interaction (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Dynamic screening of the Coulomb interaction is included to calculate electron transport coefficient (electron thermal conductivity) in the fluid limit for an unmagnetized plasma. Calculated results show that the dynamic screening effect can reduce electron thermal conductivity and may be important for low-Z plasma with very large electron–ion temperature ratio (Te/Ti(approximately-greater-than)103). © 2000 American Institute of Physics.

    Influence of Rayleigh scattering on the ion feature of Thomson scattering spectrum from a partially stripped plasma (2001)

    Notes: Studied in this paper is the influence of Rayleigh scattering on the ion feature of the Thomson scattering spectrum from a partially stripped plasma. The result shows that the profile of the scattering spectrum is nearly the same as that of Thomson scattering with inclusion of Rayleigh scattering, but the intensity of the scattering signal may be remarkably different from that of Thomson scattering. © 2001 American Institute of Physics.

    Experimental observation of ion-acoustic waves in an inhomogeneous dusty plasma (2001)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 8 (2001), S. 1459-1462

    ISSN: 1089-7674
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The propagation of a dust-ion-acoustic wave (DIAW) wave down the steep density gradient in an inhomogeneous diffusive dusty plasma is experimentally studied. It is observed that the presence of the dust enhances the plasma inhomogeneity. The phase velocity of the DIAW increases rapidly with distance and becomes supersonic. The interplay between the effects of the density nonuniformity and collisional damping results in the continuous transition of the relative amplitude of the DIAW from damping to growth. The experimental data are in agreement with theoretical prediction and confirm the importance of density-dependent ion–dust collisions. © 2001 American Institute of Physics.

    The dynamic form factor for ion-collisional plasmas (1999)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Based on the fluctuation-dissipation theorem, this work is concerned with the dynamic form factor of Thomson scattering for ion-collisional plasmas. The main effort is to calculate the ion susceptibility by analytically solving the linearized ion Fokker–Planck equation through the Chang–Callen 13-moment approach. Comparison to other theories shows that this theory can provide an accurate prediction of the position and width for ion-acoustic peaks and a proper description of the entropy wave with some underestimation of its damping. The theory may be useful for explaining experimental data and making measurement more precise. © 1999 American Institute of Physics.
