    Notes: The applicability of incoherent Thomson scattering measurement is expanded to a class of non-Maxwellian plasmas which can be described by generalized Lorentzian (kappa) distributions. A fully relativistic scattering spectrum is presented in an analytic form which allows the possibility of a more robust estimation of the bulk electron temperature in the existence of high energy tail component. © 1996 American Institute of Physics.

    Adhesion between Te-based alloy films and fluorocarbon sublayers during the ablative hole opening process (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Adhesion between thin Te-based alloy films and fluorocarbon polymer sublayers, prepared by sputtering or plasma polymerization, was investigated by observing the 1 μm-sized ablative hole opening process with a focused laser beam. Interpretations of the mechanisms for the change in energy required for the hole opening and pit geometry were based on the framework of studies of the ablative hole opening process for optical recording. Observations suggest that the molten material flow during the hole opening includes a ductile fracture and a viscous flow of the molten sublayer material as well as of active layer material. Adhesion acts as an energy barrier against the above mentioned flow of molten material during the hole opening process. Since the fluorocarbon films used in the present work had highly cross-linked structures, the adhesion was mainly dominated by the dynamic force of adhesion. Therefore, the hole opening process was mainly affected by the dynamic force of adhesion rather than the static force, which is dominated by the surface energy of the sublayer. There was a good correlation between the dynamic force of adhesion estimated by the peel-off strength and the concentrations of the -CF- and -C-CF- structures estimated from C1s spectra obtained by x-ray photoelectron spectroscopy. © 1995 American Institute of Physics.

    Thermal behavior of deep levels correlated with iron in silicon metal-oxide-semiconductor structure (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Thermal behavior of deep levels correlated with iron in Si MOS (metal-oxide-semiconductor) structure has been studied by isothermal capacitance transient spectroscopy. As a result, it is shown that interstitial iron scarcely affects the interface trap (Nt) of MOS structure. This is made clear by measuring Nt of Si MOS diodes containing iron impurity, the interstitial component of which is controlled by low temperature annealings. In addition, the low temperature (400 °C) annealing decreases interstitial iron concentration as well as interface trap density. This phenomenon is very lucky for Si MOS devices. © 1995 American Institute of Physics.

    Laser oscillation mechanisms of KrF-laser-pumped iron vapor plasma (1995)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: In order to study laser oscillation mechanisms of a KrF-laser-pumped iron vapor plasma, the population densities of iron atoms, the temperature, and the electron density in iron vapor plasma have been measured. The iron vapor plasma was produced from an iron plate by irradiation with a pulsed YAG laser (2 J/pulse). The population density of the ground-state iron atoms is about 1014–1015 cm−3, the temperature is about 5000–20 000 K, and the electron density is about 1013–1016 cm−3. When a KrF laser of 34 mJ/pulse irradiates the iron vapor plasma, the absorption cross section of the KrF laser by the iron atom is about 10−16–10−15 cm2. An optical gain has been calculated on the basis of the experimental results, and it is compared with the gain measured experimentally. © 1995 American Institute of Physics.

    Beam combiner for transient phenomena measurement in the JT-60 Thomson scattering diagnostic (1995)

    Notes: A beam combine method of two ruby lasers has been developed for the JT-60 Thomson scattering system, that is mainly composed of a polarizer plate and a Faraday rotator. By this method we have achieved a minimum time interval of 2 ms between the two laser pulses homogeneously combined. Also a high energy transmission of more than 95% has been attained. As a result, transient phenomena measurement can be available especially for pellet-injected plasmas by using the Thomson scattering system. The beam combine method applied to JT-60 is very attractive in terms of upgrading a Thomson scattering system to a high repetition diagnostic without any essential change of the existing equipment, and has been working with no serious trouble since 1989. The application of this method to a multilaser system with three or more lasers is also discussed for the practical purpose of improving a repetition rate of high power pulsed laser. © 1995 American Institute of Physics.

    Gain characteristics of gain-guided II–VI laser diodes (1996)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 69 (1996), S. 3893-3895

    Notes: We have studied the gain characteristics of gain-guided quantum well II–VI laser diodes by measuring the amplified spontaneous emission spectra under several pulsed conditions. The temperature rise during one current pulse affects the gain characteristics and the L-I characteristics. The net modal gain at constant peak current increases with the pulse width. The peak gain for long pulses shows a superlinear dependence on injection current. In this case, the L-I curve is very steep above threshold and sometimes shows an internal quantum efficiency of more than unity. This leads to an underestimation of the internal cavity loss giving a value inconsistent with the one obtained from the gain spectra. With short pulse currents (〈200 ns), the peak gain shows a weak sublinear dependence on injection current. The cavity losses obtained from the gain spectra and the L-I characteristics at short pulses are consistent. As a result, we obtain the intrinsic gain characteristics of gain-guided quantum well II–VI laser diodes. © 1996 American Institute of Physics.

    Induction of carcinomas and sarcomas by 9,10-dimethyl-1,2-benzanthracene administration into the hamster maxillary sinus (1995)

    Notes: To determine whether the local administration of 9,10-dimethyl-1,2-benzanthra-cene (DMBA) into the hamster maxillary sinus induced carcinoma at the injected site, hamsters were injected with 30 μl of 0.5% solution of DMBA in dimethyl sulfoxide (DMSO) through the infraorbital foramen into the maxillary sinus once weekly for 10 weeks (Group 2). Another group of hamsters (Group 1) received similar injections of 30 μl of DMSO only. In a third group of animals (Group 3), a roll of oxycellulose was inserted into the maxillary sinus and 40 μl of a 2% solution of DMBA in DMSO was injected once. Sinonasal carcinomas were demonstrated in 73% (8/11) of the hamsters in Group 2 and sarcomas were shown in 73% (8/11) of the hamsters in Group 3, as well as some carcinomas. No tumors were seen in the Group 1 hamsters. Histologic examination revealed squamous cell carcinomas arising from the surface epithelium and submucous glands of the nasal cavity and maxillary sinus. These findings indicate that the intrasinal administration of a 0.5% solution of DMBA in DMSO is a reliable method for inducing maxillary sinus cancer.

    Notes: summary Many surgical methods have been developed for reconstruction of extensive defects resulting from resection of lower lip cancer, with the aim of achieving of normal appearance and function. However, observers' subjective evaluation, which is the method usually employed, makes comparison of the outcomes of appearance and function obtained from different techniques difficult. In this paper, a speech intelligibility test and electromyography were used as objective means of evaluating the motor function of the reconstructed lower lip.
