- W2491440927 abstract "ABSTRACT Hollow cathode discharge lamps (HCLs) have been successfully used in recent years as calibration sources ofoptical astronomical spectrographs. The numerous narrow metal lines have stable wavelengths, which makesthem well suited for m/s calibration accuracy of high-resolution spectrographs, while the bu er-gas lines are lessstable and less useful. Accordingly, an important property is the metal-to-gas line-strength ratio (R metal=gas ).Processes inside the lamp cause the light to be emitted from di erent regions between the cathode and theanode leaing to the emission of di erent beams with di erent values of R metal=gas . We used commercially-available HCLs to measure and characterize these beams with respect to their spatial distribution, their angleof propagation relative to the optical axis, and their values of R metal=gas . We conclude that a good imaging ofan HCL into a ber-fed spectrograph would consist of an aperture close to its front window in order to lterout the parts of the beam with low R" @default.
