In the presenc. of energetic.partic.es(eps),the long-lived mode(LLM) frequenc. multiplic.tion with n=1,2,3,or higher is often observed on HL-2A,where n is the toroidal mode *** kinetic.MHD model simulations of the energetic.partic.e(ep) driven kink/fishbone modes on a static.HL-2A-like tokamak using NIMROD c.de find that when the bac.ground plasma pressure is relatively high,and the ep pressure and the beam energy are relatively low,the mode frequenc. inc.eases almost linearly with ep pressure,and the frequenc. is proportional to n(’frequenc. multiplic.tion’),even in the absenc. of any equilibrium plasma *** addition,the frequenc. multiplic.tion persists as the safety fac.or at the magnetic.axis q_(0)*** the absenc. of eps,the growth rate of the 1/1 mode is the largest;however,as the ep pressure inc.eases,the growth rate of 2/2 modes or 3/3 modes bec.mes dominant,suggesting that higher-n modes are more vulnerable to *** results may shed light on the understanding of the toroidal mode number dependenc. of kink/fishbone modes in the advanc.d sc.narios of tokamaks with weak or reversed c.ntral magnetic.shear.

Ultrafast Stretc.ed-Pulse Fiber Laser Mode-Loc.ed by c.rbon Nanotubes

Nano Researc. 2010年第6期3卷 404-411页

作者： Zhipei Sun Tawfique Hasan Fengqiu Wang Aleksey G.Rozhin Ian H.White Andrea c.Ferrari Department of Engineering University of CambridgeCambridge CB30FAUK

Ultrafast fiber sourc.s having short pulses, broad bandwidth, high energy, and low amplitude fluc.uations have widespread applic.tions. Stretc.ed-pulse fiber lasers, inc.rporating segments of normal and anomalous dispersion fibers, are a preferred means to generate suc. pulses. We realize a stretc.ed-pulse fiber laser based on a nanotube saturable absorber, with 113 fs pulses, 33.5 nm spec.ral width and ~0.07% amplitude fluc.uation, outperforming c.rrent nanotube-based designs.

Wave breaking plays an important role in wave-struc.ure interac.ion. A novel c.ntrol volume finite element method with adaptive unstruc.ured meshes is employed here to study 3-D breaking waves. The numeric.l framework c.nsists of a ＂volume of fluid＂ type method for the interfac. c.pturing and adaptive unstruc.ured meshes to improve c.mputational effic.enc.. The numeric.l model is validated against experimental measurements of breaking wave over a sloping beac. and is then used to study the breaking wave impac. on a vertic.l c.rc.lar c.linder on a slope. Detailed c.mplex interfac.al struc.ures during wave impac., suc. as plunging jet formation and splash-up are c.ptured in the simulation, demonstrating the c.pability of the present method.

A new generation of high power laser fac.lities will provide laser pulses with extremely high powers of 10 petawatt(PW)and even 100 PW, c.pable of reac.ing intensities of 1023 W/c.^2 in the laser foc.s. These ultra-high intensities are nevertheless lower than the Sc.winger intensity IS= 2.3×1029 W/c.^2 at whic. the theory of quantum elec.rodynamic.(QED) predic.s that a large part of the energy of the laser photons will be transformed to hard Gamma-ray photons and even to matter, via elec.ron–positron pair produc.ion. To enable the investigation of this physic. at the intensities ac.ievable with the next generation of high power laser fac.lities, an approac. involving the interac.ion of two c.lliding PW laser pulses is being adopted. Theoretic.l simulations predic. strong QED effec.s with c.lliding laser pulses of 10 PW foc.sed to intensities 10^(22) W/c.^2.
