1. Asymmetrically cut crystal pair as x-ray magnifier for imaging at high intensity laser facilities.
Published: 10/20/2010
Authors: Lawrence T Hudson, Albert Henins, C.I Szabo, U. Feldman, John F Seely, John J Curry
Abstract: The potential of an x-ray magnifier prepared from a pair of asymmetrically cut crystals is studied to explore high energy x-ray imaging capabilities at high intensity laser facilities. OMEGA-EP and NIF when irradiating mid and high Z targets can be ...

2. Quantitative X-ray Absorption Imaging With a Broadband Source: Application to High-Intensity Discharge Lamps
Published: 7/4/2008
Author: John J Curry
Abstract: We analyze the case of x-ray absorption imaging in which the x-ray source is broadband and the detector does not provide spectral resolution. Our particular interest is in the observation of the Hg vapor distribution in high-intensity discharge lamps ...

3. X-Ray Induced Fluorescence Measurement of Segregation in a DyI3 Metal-Halide Lamp
Published: 4/19/2007
Authors: T Nimalisuriya, John J Curry, Craig J Sansonetti, E J Ridderhof, S Shastri, A J Flikweert, W W Stoffels, M Haverlag, J JAM van der Mullen
Abstract: X-ray induced fluorescence measurements, using high energy synchrotron radiation generated on the Sector 1 Insertion Device beamline at the Advanced Photon Source, were performed on a metal-halide lamp containing Hg and DyI$_{3}$. Density distributio ...

4. Temperature Profiles and Thermal Losses in 150 Watt High-Intensity Discharge Lamps
Published: 8/19/2005
Authors: John J Curry, Craig J Sansonetti, J C.F. Wang
Abstract: A series of 150 W quartz metal-halide test lamps containing four different chemistries has been studied with optical emission spectroscopy and x-ray absorption imaging. The four chemistries are pure Hg, Hg-HgI$_2$, Hg-NaI, and Hg-NaI-DyI$_3$. Core t ...

5. X-Ray Absorption Imaging of High-Pressure Lighting Plasmas
Published: 4/1/2005
Authors: John J Curry, Craig J Sansonetti
Abstract: X-ray absorption has been used to image the distribution of Hg in high-pressure arc lamps used for lighting (Curry, Sansonetti, and Wang, in progress). Here, several images are presented showing the analytic transformation of raw x-ray data into an i ...

9. Power Balance in Highly Loaded Fluorescent Lamps
Published: 10/28/2004
Authors: G G Lister, John J Curry, James E. Lawler
Abstract: Discrepancies reported in the literature between numerical predictions and experimental measurements in low-pressure Hg discharges at high current densities are considered. A one-dimensional fluid model and recent spectroscopic and Langmuir probe me ...

10. A Compilation of Wavelengths, Energy Levels, and Transition Probabilities for Ba I and Ba II
Published: 8/13/2004
Author: John J Curry
Abstract: Energy levels, wavelengths, and transition probabilities for Ba I and Ba II have been compiled. The data are obtained from a critical evaluation of experimental measurements, and some transition probability calculations, described in the literature.
