Title: Preparing SITELLE for astronomy's roaring decade

Presenter: Marc Baril


The SITELLE imaging Fourier transform spectrograph continues to achieve impressive science results, standing in a class of its own in terms of simultaneously delivering a wide field of view (10.5' square), and a well-matched mid-range resolving power (R=2000-4000, typical). This presentation will outline improvements made to the instrument since its arrival at CFHT in the summer of 2016. The emphasis will be on recent work to improve the image quality of the instrument, as well as plans to improve the stability of the metrology and servo system of the interferometer scanning mirror. We anticipate that the combination of an IQ that will take better advantage of the exceptional seeing on Mauna Kea, and a more stable metrology system that will both benefit operational stability and characterization of the science results, will allow SITELLE to fully achieve and even exceed the goals set out at its inception, securing its place in the next decade of astronomy.
