Why ring regenerative amplification (regen)?
(Springer-Verlag, 2002-06)
We show that ring cavity regenerative amplifiers (regens) have distinct advantages over the linear ones for applications in chirped pulse amplification. Larger energy, better contrast and better isolation from the oscillator ...
Profiling and modeling of dc nitrogen microplasmas
(The American Institute of Physics, 2003-09-01)
This article explores electric current and field distributions in dc microplasmas, which have distinctive characteristics that are not evident at larger dimensions. These microplasmas, which are powered by coplanar thin-film ...
Holographic gravitational anomalies
(IOP Publishing Ltd, 2006-01-01)
In the AdS/CFT correspondence one encounters theories that are not invariant under diffeomorphisms. In the boundary theory this is a gravitational anomaly, and can arise in 4k+2 dimensions. In the bulk, there can be ...
The microwave spectrum, ab initio analysis, and structure of the fluorobenzene–hydrogen chloride complex
(The American Institute of Physics, 2003-05-22)
The fluorobenzene–hydrogen chloride π-hydrogen-bonded complex has been studied by high resolution microwave spectroscopy and ab initio calculations. Rotational spectra of the C6H5F–H35Cl,C6H5F–H35Cl, C6H5F–H37Cl,C6H5F–H37Cl, ...
Synthesis and magnetic properties of CoPt nanoparticles
(The American Institute of Physics, 2004-06-01)
High magnetocrystalline anisotropy CoPt particles with an average size of 8 nm were synthesized by the superhydride reduction of CoCl2CoCl2 and Pt(acac)2Pt(acac)2 at a high temperature. As-made particles showed a disordered ...
Ion characteristics of laser-produced plasma using a pair of collinear femtosecond laser pulses
(The American Institute of Physics, 2003-07-21)
Femtosecond laser-pulse absorption is studied in silicon ablation plasmas by means of a pair of identical 1016 W/cm21016W/cm2 collinear pulses separated on a picosecond time scale. The second laser-pulse modifies ionic ...
Self-assembled morphologies of monotethered polyhedral oligomeric silsesquioxane nanocubes from computer simulation
(The American Institute of Physics, 2005-11-08)
Self-assembly of functionalized nanoscale building blocks is a promising strategy for “bottom-up” materials design. Recent experiments have demonstrated that the self-assembly of polyhedral oligomeric silsesquioxane (POSS) ...
Computer-aided simulation of a rotary sputtering magnetron
(The American Institute of Physics, 2004-06-01)
In the past, computer-aided simulation of sputtering magnetron has been applied mainly to planar cathodes with flat target surfaces. In this work, we have simulated the target erosion profile of a cylindrical rotary magnetron ...
Thin-film ferromagnetic semiconductors based on Sb2−xVxTe3Sb2−xVxTe3 with TCTC of 177 K177K
(The American Institute of Physics, 2005-09-12)
Thin-film ferromagnetic semiconductors Sb2−xVxTe3Sb2−xVxTe3 with the Curie temperature as high as 177 K177K were prepared on sapphire (0001) substrates by molecular-beam epitaxy. Films of Sb2−xVxTe3Sb2−xVxTe3 with xx up ...
Internal plasma potential profiles in a laboratory-model Hall thruster
(The American Institute of Physics, 2001-02)
The Plasmadynamics and Electric Propulsion Laboratory High-speed Axial Reciprocating Probe system is used in conjunction with a floating emissive probe to measure plasma potential in the discharge chamber of the P5 Hall ...
