3All-optical μ^- acceleration in the laser wakefield显示文摘Muons produced by the Bethe–Heitler process from laser wakefield accelerated electrons interacting with high Z materials have velocities close to the laser wakefield. It is possible to accelerate those muons with laser wakefield directly.Therefore for the first time we propose an all-optical ‘Generator and Booster’ scheme to accelerate the produced muons by another laser wakefield to supply a prompt, compact, low cost and controllable muon source in laser laboratories. The trapping and acceleration of muons are analyzed by one-dimensional analytic model and verified by two-dimensional particle-in-cell(PIC) simulation. It is shown that muons can be trapped in a broad energy range and accelerated to higher energy than that of electrons for longer dephasing length. We further extrapolate the dependence of the maximum acceleration energy of muons with the laser wakefield relativistic factor γ and the relevant initial energy E_0. It is shown that a maximum energy up to 15.2 GeV is promising with γ = 46 and E_0= 1.45 Ge V on the existing short pulse laser facilities.F.Zhang Z.G.Deng L.Q.Shan Z.M.Zhang B.Bi D.X.Liu W.W.Wang Z.Q.Yuan C.Tian S.Q.Yang B.Zhang Y.Q.Gu 2018High Power Laser Science and Engineering2018,6,4:0
4PREPARATION OF LEAD-ACID BATTERY USING ELECTROPLATED RETICULATED SiC AS THE POSITIVE CURRENT COLLECTOR显示文摘The possibility of using Pb-electroplated reticulated SiC as the positive current collector for lead-acid batteries was investigated. Reticulated SiC with two aperture sizes (3 and 2mm) were tested as the substrate of positive electrode. It was found that the reticulated SiC has an excellent corrosion resistance in H2SO4 solution, and the Pb layer electroplated on reticulated SiC showed analogous electrochemical behavior to metal Pb. Preliminary test of the battery performance indicated that the utilization efficiency of the positive active mass of new designed batteries are improved compared with the conventional batteries. The improvement could be ascribed to the high specific surface area of the reticulated structured positive current collector, which was further supported by the even better performance of the battery made from a smaller aperture size (2mm) reticulated SiC as the substrate of the positive electrode.Z.M.Zou X.M.Cao C.Tian J.S.Zhang 2005Acta Metallurgica Sinica(English Letters)2005,18,2:0
