JouFLU: upgrades to the Fiber Linked Unit for Optical Recombination (FLUOR) interferometric beam combiner
Abstract
The Fiber Linked Unit for Optical Recombination (FLUOR) is a precision interferometric beam combiner operating at the CHARA Array on Mt. Wilson, CA. It has recently been upgraded as part of a mission known as "Jouvence of FLUOR" or JouFLU. As part of this program JouFLU has new mechanic stages and optical payloads, new alignment systems, and new command/control software. Furthermore, new capabilities have been implemented such as a Fourier Transform Spectrograph (FTS) mode and spectral dispersion mode. These upgrades provide new capabilities to JouFLU as well as improving statistical precision and increasing observing efficiency. With these new systems, measurements of interferometric visibility to the level of 0.1% precision are expected on targets as faint as 6th magnitude in the K band. Here we detail the upgrades of JouFLU and report on its current status.

© 2014 SPIE. The CHARA Array, operated by Georgia State University, was built with funding provided by the National Science Foundation, Georgia State University, the W. M. Keck Foundation, and the David and Lucile Packard Foundation. The CHARA Array is currently funded by the National Science Foundation under Grant AST-0606958. Additional funding for the Jouvence of FLUOR upgrade project was provided by ANR EXOZODI. Research conducted with FLUOR has made use of NASA's Astrophysics Data System and of the SIMBAD database, operated at CDS (Strasbourg, France).Attached Files
