Self-consistent nonstationary two-dimensional model of multipactor in dielectric-loaded accelerator structures
Posted on July 6th, 2009 No commentsO. V. Sinitsyn, G. S. Nusinovich, and T. M. Antonsen, Jr.<br/> In this paper, a self-consistent nonstationary two-dimensional model of multipactor in dielectric-loaded accelerating structures is proposed. In comparison with existing models, this model calculates dc electric field produced by secondary electrons self-consistently and it also includes effects of … [Phys.

Surface energy transport following relativistic laser-solid interaction
Posted on July 6th, 2009 No commentsH. Langhoff, B. T. Bowes, M. C. Downer, Bixue Hou, and J. A. Nees<br/> A planar Al target is excited by a 25 fs laser pulse focused to intensity up to 3 x 10 W/cm in a ~1 [mu]m radius spot; subsequent heat propagation along the target surface, imaged by a delayed probe pulse, appears as a roughly circular area of reduced reflectivity centered on the pump spot, that e … [Phys.

An improved X-band magnetically insulated transmission line oscillator
Posted on July 6th, 2009 No commentsJin-Chuan Ju, Yu-Wei Fan, Hui-Huang Zhong, and Ting Shu<br/> This paper presents an improved X-band magnetically insulated transmission line oscillator (MILO) design that addresses several deficiencies found in previous experiments. In the new structure, an improved design of the launch point region is introduced, which improves the electric field uniformity … [Phys. Plasmas 16, 073103 (2009)] published Mon Jul 6, 2009.

Generation of a dressed soliton in a four-component dusty plasma with nonthermal ions
Posted on July 6th, 2009 No commentsPrasanta Chatterjee, Ganesh Mondal, Kaushik Roy, S. V. Muniandy, S. L. Yap et al.<br/> Dust acoustic solitary wave mechanicss are studied in a four-component dusty plasma. Positively and negatively charged mobile dust and Boltzmann-distributed electrons are considered. The ion distribution is taken as nonthermal. The Kortewegde Vries equation is derived using reductive perturbation technique. W … [Phys. Plasmas 16, 072102 (2009)] published Mon Jul 6, 2009.

Functional regularity properties for light rays in general relativity
Posted on July 6th, 2009 No commentsRoberto Giambo, Fabio Giannoni, and Antonio Masiello<br/> In this note we consider some functionals restricted to the nonholonomic constraint satisfied by lightlike curves in Lorentzian manifolds. These functionals are related to the arrival time map, whose critical points are light rays in general relativity, and they have been used in the variational the … [J. Math.

Rapid piezoelectric response and origin in (001) Pb(InNb)TiO crystal
Posted on July 6th, 2009 No commentsC.-S. Tu, R. R. Chien, S.-C. Lee, V. H. Schmidt, and H. Luo<br/> Normal piezoelectric coefficient d, domain structure, and x-ray diffraction of a (001)-cut Pb(InNb)TiO (PIN-30%PT) single crystal have been investigated as a function of poling electric (E) field. E-field-dependent domain structures were observed by using a polarizing microscope. Piezoelectric coeff … [J. Appl. Phys. 106, 016102 (2009)] published Mon Jul 6, 2009.
