    Description: New objectively balanced observation-based reconstructions of global and continental energy budgets and their seasonal variability are presented that span the golden decade of Earth-observing satellites at the start of the twenty-first century. In the absence of balance constraints, various combinations of modern flux datasets reveal that current estimates of net radiation into Earth’s surface exceed corresponding turbulent heat fluxes by 13–24 W m−2. The largest imbalances occur over oceanic regions where the component algorithms operate independent of closure constraints. Recent uncertainty assessments suggest that these imbalances fall within anticipated error bounds for each dataset, but the systematic nature of required adjustments across different regions confirm the existence of biases in the component fluxes. To reintroduce energy and water cycle closure information lost in the development of independent flux datasets, a variational method is introduced that explicitly accounts for the relative accuracies in all component fluxes. Applying the technique to a 10-yr record of satellite observations yields new energy budget estimates that simultaneously satisfy all energy and water cycle balance constraints. Globally, 180 W m−2 of atmospheric longwave cooling is balanced by 74 W m−2 of shortwave absorption and 106 W m−2 of latent and sensible heat release. At the surface, 106 W m−2 of downwelling radiation is balanced by turbulent heat transfer to within a residual heat flux into the oceans of 0.45 W m−2, consistent with recent observations of changes in ocean heat content. Annual mean energy budgets and their seasonal cycles for each of seven continents and nine ocean basins are also presented.

    Notes: Boron doping into silicon has been investigated using an ArF excimer laser. Dopant atoms are obtained by pyrolysis of BF3. Two kinds of doping, the doping in BF3 ambients and the doping using adsorbed layers, have been performed. In both cases, the sheet resistance decreases with increasing the number of pulses. The surface concentration and the junction depth increase with the number of pulses. From these results, it is found that dopant atoms are supplied from only adsorbed layers of BF3 formed on the silicon surface. Moreover, the supply of dopant atoms from adsorbed layers limits the doping process.

    Notes: A design of a microspectrophotometric system using a synchrotron radiation (SR) source is described. The system covers a wide spectral range of 50–13000 cm−1, being under construction at the UVSOR BL6B beamline in the Institute for Molecular Science. Preliminary experiments in the mid-infrared region (500–5000 cm−1) have qualitatively confirmed the theoretical calculation that the synchrotron radiation is more intense than a blackbody (T=1200 K) when a microspectrophotomeric technique is applied, which is due to natural collimation and high brilliance of SR source. The SR as an infrared source exhibits its advantage on measuring the spectra of small single crystals especially in the far-infrared region.

    Notes: By using a particle-in-cell simulation code which includes tunneling ionization, it is found that strong wake fields are excited and amplified due to the modulation of an intense laser pulse induced by an ionizing plasma in the regime where the matching condition between laser pulse length (LLaser) and plasma wavelength (λp), i.e. LLaser≤λp is not satisfied. The modulation is characterized by a gradual steepening of the pulse front where there is a copropagating density gradient which is due to the rapid plasma formation from ionization there. Accordingly, the wake field is convectively amplified to a significant level. This amplification of plasma waves always occurs, more or less, for laser propagation in ionizing plasmas. © 1998 American Institute of Physics.

    Notes: The self-similar distribution of electrons is found for a nonuniform underdense plasma that is heated by an intensive laser field. The distribution function is flat-topped for the low-energy electrons. And in the high-energy region, it has a well-pronounced high-energy tail. It is also found how the electron heat flux and the absorption coefficient depend upon both the ratios of electron mean-free path to the inhomogeneity scale of effective temperature and of the oscillation velocity to the thermal velocity. The actual shapes of electron energy distribution, the heat flux limitation, and the electromagnetic radiation absorption rate are given, both for a currentless plasma and for a plasma with a finite electric current. © 1995 American Institute of Physics.

    Notes: The nonlinear interaction of an ultrashort-pulse laser with a solid target is investigated by using a newly developed particle simulation code, which enables the analysis of laser–plasma interaction in the very steep density gradient in which the laser light penetrates into an overdense plasma. For an ultrashort laser pulse, the plasma density scale length Ld satisfies Ld≤r0 for an electron excursion length r0. Laser absorption and electron acceleration processes are proposed for the above situation. It is found that the wave breaking is the main mechanism of the electron acceleration and laser absorption, as is discussed in Brunel's paper [Phys. Rev. Lett. 59, 52 (1987)].

    Notes: The design of the next generation synchrotron radiation ring is based on a low-emittance storage ring with large numbers of zero-dispersion straight-section for insertion devices. As a candidate, the Chasman-Green lattice is likely to be the most promising to be investigated. In this paper, field gradients and edges which are not perpendicular to the optic axis are proposed to introduce the bending magnets for a low-emittance Chasman-Green lattice. The horizontal beam emittance of a large ring is generally expressed as1 (1) εx=Cqγθ3F(ψ)/Jx, where Cq=3.83×10−13 m, γ=Lorentz factor of the stored beam, θ=bending angle of a dipole magnet, F(ψ)=emittance form factor as a function of the betatron phase advance per half cell ψ, Jx=partition number of the horizontal betatron oscillation.The form factor F(ψ) depends on the lattice structure and is expressed for the symmetrical cell as (2) F(ψ)=(1/ρθ3)(1/ρθ) ∫ρθ0(γη2 +2αηη'+βη'2)ds, where H=γη2+2αηη'+βη'2 is the Courant–Snyder dispersion invariant, ρ is the magnetic radius, α, β, γ are Twiss parameters and η, η' are the dispersion function and the derivative with s the integral ranges over a bending magnet. We calculate, for examples, F(ψ) for a single lens approximation of equal focal length with ρ=25 and θ=π/32 radian. For the gradient magnet, the gradient parameter K is taken to be −0.05(1/m2) for example, where K is defined as (3) K=(1−n)/2, n=−(ρ/B)(dB/dx). The absolute value of K is restricted to be small to guarantee the damping of energy oscillation. For a nonperpendicular edge, the angle between the edge normal and the beam axis is chosen to be −0.255 radian, for example. The sign conversion is in the usual manner.2 The form factor F(ψ) is calculated as a function of Ψ for the two examples. Another factor to effect the emittance is the partition number Jx as seen in Eq. (1).Jx can be written as (4) Jx=1−Kρ2θ2/3, in the first-order calculation. A negative K has little effect to decrease the emittance in cooperation with F(ψ). The horizontal beam emittance is shown to be decreased by the reduction of the factor in two examples in cooperation with the increase of the horizontal damping partition number of the betatron oscillation.
