Performance of the GHRS Pt-Ne Hollow-Cathode Lamps After Their Return From Space and Comparison With Archival Data

May 1, 2006
Author(s)
F Kerber, D Lindler, P Bristow, Gillian Nave, Joseph Reader, Craig J. Sansonetti, D Lembke, S Heap, Michael R. Rosa, H J. Wood
The Space Telescope European Co-ordinating Facility (ST-ECF) and the National Institute of Standards and Technology (NIST) are collaborating to study hollow cathode calibration lamps as used onboard the Hubble Space Telescope (HST). As part of the STIS

The Spectrum of Th-Ar Hollow-Cathode Lamps in the 900 nm to 4500 nm Region: Establishing Wavelength Standards for the Calibration of VLT Spectrographs

May 1, 2006

F Kerber, Gillian Nave, Craig J. Sansonetti, P Bristow, A Rosa, H-U Kaufl, Michael R. Rosa
The European Southern Observatory (ESO), the Space Telescope European Co-ordinating Facility (ST-ECF), and the National Institute of Standards and Technology (NIST) are collaborating to study Th-Ar hollow cathode lamps as used for the calibration of VLT

X-Ray Absorption Imaging of High-Pressure Lighting Plasmas

April 1, 2005
Author(s)
John J. Curry, Craig J. Sansonetti
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 image

Coincidence in the Two-Photon Spectra of Li and Li 2 at 735 nm

February 1, 2005
Author(s)
W DeGraffenreid, Craig J. Sansonetti
A coincidence between the 2S - 3S two-photon transition in the spectrum of atomic Li and the X 1Sg+ E 1Sg two-photon ro-vibrational series of 7Li2 was observed near 735 nm in a heat pipe oven using a tunable laser and thermionic diode detection scheme. The

Aging of Spectral Lamps in Space

High-Resolution Observations of the Infrared Spectrum of Neutral Neon

September 1, 2004
Author(s)
Craig J. Sansonetti, M M. Blackwell, Edward B. Saloman
We have observed the spectrum of neutral neon (Ne I) emitted by a microwave-excited electrodeless discharge lamp with the National Institute of Standards and Technology 2-m Fourier transform spectrometer. The spectra cover the regions 6929 to 11000 with a

Characterization of the Far-Ultraviolet Spectrum of Pt/Cr-Ne Hollow Cathode Lamps as used on the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope

August 1, 2004
Author(s)
Craig J. Sansonetti, Joseph Reader, F Kerber, Michael R. Rosa
We report laboratory measurements to characterize the spectral output of platinum/chromium hollow cathode lamps containing neon carrier gas. The spectrum was recorded photographically with the NIST 10.7-m normal-incidence spectrograph. The lamps
