ISSN: 1573-2991Source: Springer Online Journal Archives 1860-2000Topics: BiologyEnergy, Environment Protection, Nuclear Power EngineeringNotes: Summary Since 1977, stringent environmental regulation has been progressively imposed on Malaysia's most polluting industry, the palm oil mills. The impact of the regulation on international trade and producer welfare has been quite small compared to the relative benefits to society in terms of changes in the levels of dissolved oxygen in the industrial effluents. External benefits from pollution abatement have been derived. This paper presents a preliminary evaluation of the derived benefits which have a long- term potential of recycling valuable resources while maintaining competitiveness in the international palm oil trade.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1089-7674Source: AIP Digital ArchiveTopics: PhysicsNotes: The Rayleigh–Taylor (RT) instability, which occurs when a lower-density fluid accelerates a higher-density layer, is common in nature. At an ablation front a sharp reduction in the growth rate of the instability at short wavelengths can occur, in marked contrast to the classical case where growth rates are highest at the shortest wavelengths. Theoretical and numerical investigations of the ablative RT instability are numerous and differ considerably on the level of stabilization expected. Presented here are the results of a series of laser experiments designed to measure the RT dispersion curve for a radiatively driven sample. Aluminum foils with imposed sinusoidal perturbations ranging in wavelength from 10 to 70 μm were ablatively accelerated with a radiation drive generated in a gold cylindrical hohlraum. A strong shock wave compresses the package followed by an ∼2 ns period of roughly constant acceleration and the experiment is diagnosed via face-on radiography. Perturbations with wavelengths ≥20 μm experienced substantial growth during the acceleration phase while shorter wavelengths showed a sharp drop off in overall growth. These experimental results compared favorably to calculations with a two-dimensional radiation-hydrodynamics code, however, the growth is significantly affected by the rippled shock launched by the drive. Due to the influence of the rippled shock transit phase of the experiment and ambiguities associated with directly extracting the physical amplitude of the perturbations at the ablation front from the simulations, direct comparison to the ablation front RT theory of Betti et al. [Phys. Plasmas 5, 1446 (1998)], was difficult. Instead, a numerical "experiment" was constructed that minimized the influence of the shock and this was compared to the Betti model showing quite good agreement. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1089-7674Source: AIP Digital ArchiveTopics: PhysicsNotes: The morphology of the 33.8 A(ring) emission from laser-irradiated targets was studied using a concave mirror with a W/B4C multilayer coating. The mirror had peak normal-incidence reflectance of 1.8% at a wavelength of 33.8 A(ring). The emissions from a variety of targets were imaged on film with a spatial resolution of 30 μm in the target plane. Radiatively heated, low-density plastic and silica foams, x-ray laser targets, and a gas-filled enclosure were imaged. Several targets were simultaneously imaged at wavelengths of 33.8 and 130 A(ring) using two normal-incidence microscopes.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1089-7674Source: AIP Digital ArchiveTopics: PhysicsNotes: In this paper we describe experimental and computational studies of multiple-pulse-driven laser plasma, which is the gain medium for a neon-like yttrium x-ray laser. Near-field emission profiles have been measured both with and without reinjection of the x-ray laser photons to couple with the amplifying medium created by later pulses using an external multilayer mirror. From the temporal and spatial evolution of the near-field emission profiles we can examine the pulse-to-pulse variation of the x-ray laser plasma due to changes in the hydrodynamics, laser deposition, and the injecting of x-ray laser photons back into an amplifying x-ray laser plasma. Using a combination of radiation hydrodynamics, atomic kinetics, and ray propagation codes, reasonable agreement has been obtained between simulations and the experimental results. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: The energy distributions of ions and electrons in the scrape-off layer of TEXT are measured with a bidirectional retarding field analyzer (RFA). The probe provides simultaneous measurements parallel and antiparallel to the plasma current. Large asymmetries in this direction in the flux and temperature that were found with the RFA appear partly due to differences in the connection lengths Lc. The measurements from the analyzer are compared with the results of a simple edge model to infer the edge particle diffusion coefficient. While the measurements are consistent with the model for longer connection lengths (∼10 m in TEXT-U), the agreement deteriorates for shorter Lc. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: Collisionally pumped soft x-ray lasers now operate over a wavelength range extending from 35 to 300 A(ring). These well-characterized sources have high peak brightness (GeV blackbody temperature) and narrow bandwidth making them ideal for x-ray imaging and interferometry. We will describe experiments which have used the yttrium neon-like x-ray laser operating at 155 A(ring) to probe plasmas at electron densities exceeding 4×1021 cm−3. The short pulse duration of this x-ray laser (∼150 ps) has made it possible to image directly driven thin foils with 1–2 μm spatial resolution. Advances in multilayer mirrors and beam splitters have now also made it possible to develop x-ray laser interferometers. We will describe initial experiments to probe plasmas relevant to ICF using x-ray laser interferometry. The progress in the development of short pulse x-ray lasers (∼30 ps) which are ultimately necessary to extend x-ray laser diagnostic techniques to higher densities will also be presented. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A retarding energy analyzer, JANUS [A. S. Wan, T. F. Yang, B. Lipschultz, and B. LeBonbard, Rev. Sci. Instrum. 57, 1542 (1986)], has been developed at MIT which has the capability of measuring the local electron temperature, ion temperature, and sheath potential in the scrape-off layer of a plasma. This offers a useful tool in the study of material development for the divertor target to be considered for ITER. The radial profile of sheath potential (φw) on tungsten surfaces has been measured in the boundary layer of Alcator C plasma using this analyzer. Simultaneous measurement of the electron temperature (Te) and ion temperature (Ti) profiles were also made. The retarding grids of the JANUS analyzer were made of fine screens, which made it difficult to determine the absolute values of the ion and electron current. A new analyzer under development replaces the screen with slits, making determination of the absolute currents, ne, and ni easier. This analyzer will be calibrated and tested on a compact tandem mirror machine, the PPEX, that is currently operational at MIT.
