Selective and non-selective excitation/ionization processes in analytical glow discharges: excitation of the ionic spectra in argon/helium mixed plasmas
, Journal of Analytical Atomic SpectrometryThe increasing use of mixed gases, including helium mixtures, in glow discharge mass spectrometry has led to a need to understand the resulting signal enhancements due to changes in excitation and ionization processes. To understand more fully these processes in glow discharge, we have carried out complementary optical emission spectrometry experiments. The presence of added gases in the plasma gas can cause major changes in the number density of plasma gas ions and metastable atoms and so affects the intensities of spectral lines involving selective and non-selective excitation & ionization processes. We report the results of an experimental investigation on the effect of Ar/He mixed plasmas on the relative emission intensities of various analyte materials including copper, iron and titanium. Selective and non-selective excitation processes which are mainly dependent on the nature of the plasma gas and analyte material are observed and discussed.

Near-magnetic-field scaling for verification of spacecraft equipment
, Geoscientific Instrumentation, Methods and Data Systems, Vol: 2, Pages: 249-255, ISSN: 2193-0864Magnetic-field measurements are essential tothe success of many scientific space missions. Outside ofthe earth’s magnetic field the biggest potential source ofmagnetic-field contamination of these measurements is emittedby the spacecraft. Spacecraft magnetic cleanliness is enforcedthrough the application of strict ground verificationrequirements for spacecraft equipment and instruments. Dueto increasingly strict AC magnetic-field requirements, manyspacecraft units cannot be verified on the ground using existingtechniques. These measurements must instead be takenclose to the equipment under test (EUT) and then extrapolated.A traditional dipole power law of −3 (with a fieldfall-off proportional to r−3) cannot be applied at these closedistances without risk of underestimating the field emitted bythe EUT, but we demonstrate that a power law of −2 is tooconservative. We propose a compromise that uses a powerlaw of −2 up to a distance equal to 3 times the unit size, beyondwhich a dipole power law can be applied. When extrapolatingfrom a distance of 0.20 m to 1.00 m from the centre ofa 0.20 m wide EUT, we demonstrate that this method avoidsan under prediction of the field, and is at least twice as accurateas performing the extrapolation with a fixed power lawof −2.

Correlations at Large Scales and the Onset of Turbulence in the Fast Solar Wind
, The Astrophysical Journal, Vol: 778, Pages: 177-177, ISSN: 0004-637XWe show that the scaling of structure functions of magnetic and velocity fields in a mostly highly Alfvénic fast solar wind stream depends strongly on the joint distribution of the dimensionless measures of cross helicity and residual energy. Already at very low frequencies, fluctuations that are both more balanced (cross helicity ~0) and equipartitioned (residual energy ~0) have steep structure functions reminiscent of "turbulent" scalings usually associated with the inertial range. Fluctuations that are magnetically dominated (residual energy ~−1), and so have closely anti-aligned Elsasser-field vectors, or are imbalanced (cross helicity ~1), and so have closely aligned magnetic and velocity vectors, have wide "1/f" ranges typical of fast solar wind. We conclude that the strength of nonlinear interactions of individual fluctuations within a stream, diagnosed by the degree of correlation in direction and magnitude of magnetic and velocity fluctuations, determines the extent of the 1/f region observed, and thus the onset scale for the turbulent cascade.
