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
Author(s)
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

Spectral Characterization of HST Calibration Lamps - New Pt/Ct-Ne Line Catalogues and Ageing Test

June 25, 2004
Author(s)
F Kerber, Michael R. Rosa, Craig J. Sansonetti, Joseph Reader, Gillian Nave, P Bristow, M Fiorentio, G Lercher
The Space Telescope European Coordinating Facility's (ST-ECF) lamp project, funded directly by the European Space Agency (ESA), is dedicated to the study of hollow cathode calibration lamps as they are used onboard the Hubble Space Telescope (HST). There

Wavelength Standards in the Ultraviolet

September 1, 2002
Author(s)
Gillian Nave, Craig J. Sansonetti
We have made accurate wavelength measurements for lines of Pt 1 and II, Fe I, Ge I, and Kr II in the region 1800 to 3100 . New microlithography tools that are currently coming into production use are based on the ArF excimer laser which operates at a

Absolute Transition Rates for Transitions From 5p Levels in Kr II

March 1, 2001
Author(s)
Krzysztof Dzierzega, Ulf Griesmann, Gillian Nave, L Bratasz
Branching ratios were measured for 155 electric dipole transitions from 5p and 5p1 levels of singly ionized Kr between 200 nm and 2400 nm. Of these, 83 were measured for the first time. Absolute transition rates for prominent lines, with uncertainties as

Accurate Transition Rates for the 5p-5s Transitions in Kr I

August 1, 2000
Author(s)
Krzysztof Dzierzega, U Volz, Gillian Nave, Ulf Griesmann
Branching fractions were measured for electric dipole transitions for the 5p upper levels to the 5s levels in neutral Krypton atoms. The measurements were made with a wall-stabilized electric arc for the spectral lines in the visible, and with a hollow
