Abstract

To provide data sharper than JWST and deeper than HST, MAVIS (the MCAO Assisted Visible Imager and Spectrograph) will be driven by a state-of-the-art real-time control (RTC) system leveraging cutting edge technologies both in terms of hardware and software. As an implementation of the COSMIC platform, the MAVIS RTC will host a hard RTC module, fed in quasi real-time with optimized parameters from its companion soft RTC. In order to meet the AO performance requirement in the visible, the overall real-time pipeline latency should be in the range of few hundreds microseconds ; and, considering the several high order wavefront sensors (WFS) of the current optical design, the specifications of the hard RTC module are very close to those contemplated for ELT first light SCAO systems, making it as an at scale pathfinder for these future facilities. In this paper, we will review the hardware and software design and prototyping activities led during phase A of the project.
