Solenoid and sextupole optics of ultra-cold atomic hydrogen beams
(Elsevier, 1993-06-20)
Analytic calculations and particle tracking simulations are presented for a polarized atomic hydrogen beam produced by extraction from a superfluid helium coated cell in a large solenoidal magnetic field. Compression of ...
Numerical Study of Coronal Mass Ejections, Shocks, and Turbulence: from Chromosphere to 1 AU.
(2014)
My dissertation focuses on one of the major source of destructive space weather: coronal mass ejections (CMEs). By helping develop and utilizing a new data-driven global MHD model: The Alfven Wave Solar Model (AWSoM) in ...
Neutron-capture gamma-ray spectra of the tungsten isotopes
(Elsevier, 1962-06)
The spectra of gamma radiation following reactor-neutron capture in separated tungsten isotopes have been measured with a three-crystal scintillation pair spectrometer as well as with a single-crystal scintillation counter, ...
Curvature and flatness in a Brans-Dicke universe
(Elsevier, 1994-06-27)
The evolution of a universe with Brans-Dicke gravity and nonzero curvature is investigated here. We find solutions to the equations of motion during the radiation dominated era. In a Friedman-Robertson-Walker cosmology we ...
Decay angular distributions of p[pi]- states formed in diffraction dissociation of neutrons on carbon
(Elsevier, 1972-08-01)
We present decay angular distributions of the p[pi]- system formed from the interactions of 25-30 GeV/c neutrons on a carbon target. The data are studied as afunction of t', which allows a partial separation of coherent ...
Multiple Compton scattering gamma ray imaging camera
(Elsevier, 1990-12-20)
With the recent advances in position sensing detectors, a compact, multiple layered, Compton scattering gamma ray imaging camera has been investigated for technological feasibility. Beginning from Kamea and Hanada's recent ...
A Flexible Spline Model of the Spin Echo with Applications to Estimation of the Spin-Spin Relaxation Time
(Elsevier, 1994-12)
Under weak mathematical assumptions, the distortion due to B0 inhomogeneity is shown to take the form of a characteristic function, which is the Fourier transform of a probability distribution, A model of the spin echo is ...
Diffraction dissociation of neutrons in the reaction dp --> ppp[pi]- at 25 GeV/c
(Elsevier, 1974-09-18)
We observe the reaction dp --> pspec (p[pi]-)p in a bubble chamber exposure at 25 GeV/c incident deuteron momentum. The (p[pi]-) system with invariant mass below 2.0 GeV is interpreted as neutron diffraction dissociation. ...
Recovery and purification of no-carrier-added [18F]fluoride with bistrimethylsilylsulfate (BTMSS)
(Elsevier, 1991)
No-carrier-added trimethylsilyl[18F]fluoride (TMS[18F]F) was rapidly liberated from a variety of dry supports containing unreactive [18F]fluoride by simply heating with neat bistrimethylsilylsulfate. The supports included ...
