Published 1991Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The Stark levels of the 4I15/2 ground state manifold have been determined for Er3+-doped fluorozirconate, fluorophosphate, phosphate, and silicate bulk glasses from fluorescence-line-narrowing (FLN) measurements at 4.2 K. Splittings between adjacent Stark levels were observed to be 10–140 cm−1 and the total energy spread of the manifold was found to range from 335 to 400 cm−1. The position of a given Stark level varies up to 60 cm−1 depending on the particular Er3+ sites excited. Using the 4.2-K results, homogeneous broadening is found to be a reasonable approximation for the 300-K luminescence band of the glasses examined. Results are also presented for silica preforms as well as for a barium-zinc-lutetium-thorium fluoride composition. The FLN studies together with a Judd–Ofelt [Phys. Rev. 127, 750 (1962); J. Chem. Phys. 37, 511 (1962)] analysis of the absorption data suggest similarities in the local environment between the fluorozirconates and the high-fluorine fluorophosphates.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The magnetic coupling of 20-nm-thick Ni and Ni78Fe22 films through intervening Ag film has been investigated by ferromagnetic resonance (FMR) at 33 GHz. Films were deposited by e-beam evaporation on glass in the order glass/Ag/Ni/Ag/NiFe/Ag. The Ag over- and underlays were 20 nm thick; the central Ag-film thickness was varied between 0 and 20 nm. The coupling of the two ferromagnetic films, A and B, through the interface is modeled by adding −KMA⋅MB to the free energy per unit area. The FMR-mode positions are found from the solutions of a quadratic in K. Subsequently, FMR-mode intensities and linewidths are computed. Input data for these calculations were obtained from observations made on uncoupled Ni and NiFe films. From in-plane dc-field date a variation of K was deduced with a coupling film thickness t of the form exp(−t/τ) with τ equal to 2.68 nm. Limited FMR data taken with the dc field normal to the specimen are consistent with a weak coupling, K∼t−0.83. Little coupling was found in a glass/SiO2/Ni/SiO2/NiFe/SiO2 sequence with the SiO2 films spanning the same thickness range as the Ag in the first sequence. It is believed that the coupling in Ni/Ag/NiFe is dominated by conduction-electron-spin polarization. Some of the coupling may be magnetostatic in origin.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: The question of an optimum exposure time for an event counting charge coupled device electron detection system is discussed [B. D. Hall, M. Flüeli, J. -P. Borel, and R. Monot, Rev. Sci. Instrum. (in press)]. The system is a null-event detector, providing a single piece of information per exposure: whether an event has not been detected. It is shown that when the number of exposure periods is fixed, optimum operation conditions require high exposures, in spite of the loss of information due to multiple events being detected as single ones.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: We developed an imaging detector to measure high-frequency fluctuations in visible and near-UV emission from tokamaks. The detector is intended for the study of plasma turbulence, mhd phenomena, and edge-localized modes. Particularly in the first two applications, it will complement existing techniques by providing higher spatial resolution as well as measurement capability in otherwise inaccessible regions of the plasma. The device consists of an optical system, a linear array of 32 photodiodes, and an amplifier for each photodiode. The amplifiers have a transimpedance gain of 105–106 and the frequency response is flat to 100 kHz. Experience with this device has shown that optical imaging systems can be easily designed and tailored to a specific measurement because of the small size and close spacing of the individual light-sensitive elements. The device has been successfully tested on TEXT-U in measurements of Hα fluctuations.Type of Medium: Electronic ResourceURL: -

ISSN: 1550-7408Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: . Developmental preadaptation of virulent stages of Trypanosoma cruzi correlates with their ability to survive and establish infection in mammalian hosts. Infective trypomastigote stages must first preadapt to survival in the extracellular milieu and then to the rigors of establishing an intracellular infection. Selected phenotypic variations in evading host defences have been correlated with expression of stage-specific proteins or functions. Resistance of trypomastigotes to complement-mediated killing correlates with the presence of a stage-specific molecule that exhibits an analogous function to mammalian decay-accelerating factor, and with the presence of a neuraminidase/trans-sialidase that transfers sialic acid moieties to the parasite surface, thereby enabling it to avoid complement activation. Trypomastigotes enter cells by a mechanism that involves sorting of cell surface receptors and avoids eliciting a respiratory burst. Once within a membrane-bound vacuole, which undergoes acidification, the neuraminidase/trans-sialidase and an acid-active, transmembrane pore-forming protein are released by the parasite and are capable of acting together to accelerate rupture of the vacuolar membrane and the parasite's escape into the cytoplasm of the host cell. Escape from the parasitophorous vacuole allows virulent stages of T. cruzi to avoid compartmental, non-oxidative killing mechanisms such as degradation by lysosomal hydrolases.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The special features of diffraction from particles in the nanometer size range are discussed and the problem of structure determination is considered. A direct method of structure analysis, known as Debye Function Analysis, is presented and evaluated. The method is capable of obtaining information about both the size and structure of domains in a sample, and can identify noncrystalline structures. Numerical simulations of observations are used to investigate the limitations of the technique, and also provide a general method for quantifying uncertainties in parameters estimated by Debye Function Analysis. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1988Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We have used ferromagnetic resonance (FMR) at 33 GHz to study the properties of a number of evaporated thin Fe film systems. Values for effective anisotropy field HKeff , g value, and exchange constant A were derived. For Fe on glass, ||HKeff || was found to increase with increasing thickness. These changes were attributed to stress which decreased with film thickness. The presence of a Cu or a Ti underlayer did not seem to affect HKeff for films grown at room temperature. However, Fe/Ti/glass films made at higher substrate temperatures, Ts, did show an increase in ||HKeff ||. The appearance of a spin-wave mode in the Fe films enables us to compute the exchange constant A for Fe, A=(2.12±0.14)×10−6 ergs cm−1. The coupling between two thin Fe films through an intervening Cu layer was investigated. A model predicting the number and position of the peaks in the spectrum as a function of coupling is presented. From experiment it was observed that the coupling remains almost constant through the 50–5-nm Cu thickness range but rises sharply at 2-nm Cu thickness.Type of Medium: Electronic ResourceURL: -

Published 1991Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: An electron diffraction apparatus is described that has been designed specifically for use with molecular beams containing small particles in the nanometer size range. A novel electron detection system has been developed, using linear charge coupled device imagers, which allows rapid parallel measurement of the diffraction signal in a direct electron counting mode. The apparatus also features a 100 kV electron gun and electron optics derived from a Philips EM 300 electron microscope. Details of the apparatus are presented and measurement results on small silver particles in a beam of helium carrier gas are also given; these are interpreted using an icosahedral structure for the small particles.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A simple event-counting technique is considered that can be implemented on detector systems with adjustable exposure times. A single measurement cycle has two steps: exposure and readout. During readout a threshold is used to discriminate against background noise, making it impossible to differentiate between single or multiple events. The actual event rate can be estimated by accumulating the results of repeated measurement cycles, and applying a correction based on the probability for multiple events to occur. By considering the uncertainty in the estimation of the event rate, and assuming a Poisson process, it is shown that optimum exposure requires an average event count per exposure of roughly 1.7. The technique is applied to a high-energy electron-counting system based on a linear CCD photodetector. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL:
