Keck all sky precision adaptive optics: project overview
Abstract
We present the status and plans for the Keck All sky Precision Adaptive optics (KAPA) program. KAPA includes four key science programs, an upgrade to the Keck I laser guide star (LGS) adaptive optics (AO) facility to improve image quality and sky coverage, AO telemetry based point spread function (PSF) estimates for all science exposures, and an educational component focused on broadening the participation of women and underrepresented groups in instrumentation. For the purpose of this conference we will focus on the AO facility upgrade which includes implementation of a new laser, wavefront sensor and real-time controller to support laser tomography, the laser tomography system itself, and modifications to an existing near-infrared tip-tilt sensor to support multiple natural guide star (NGS) and focus measurements.

© 2020 Society of Photo-Optical Instrumentation Engineers (SPIE). The W. M. Keck Observatory is operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. Funding support for the KAPA system provided by the National Science Foundation Mid Scale Innovations Program award AST-1836016 (PI: Wizinowich). The Keck II real-time controller is funded by the NSF Major Research for Instrumentation Program award AST-1727071 (Wizinowich). Funding support for the KAPA science programs is provided by the Gordon and Betty Moore Foundation through awards to UH (Liu), UCSD (Wright) and two awards to UCLA (Ghez and Treu), and sub-awards to CIT (Mawet), UCB (Lu) and UCD (Jones). Funding support for the AstroTech instrumentation intensive is provided by the Heising-Simons Foundation through UCSC (Hunter) and UCB (Lu). The turbulence simulator is supported by a grant from R. Simperman.Attached Files
