Fiber Scrambling for High-Resolution Spectrographs. II. A Double Fiber Scrambler for Keck Observatory

Abstract We have designed a fiber scrambler as a prototype for the Keck HIRES spectrograph, using double scrambling to stabilize illumination of the spectrometer and a slicer to increase spectral resolution to R ∼ 70,000 with minimal slit losses. We find that the spectral line-spread function... Full description
