Design and feasibility study of a scalable liquid mirror

On demand | Presented live 20 June 2024

Abstract

Advancements in ground-based liquid mirror telescopes that enable tilt and slew while maintaining mirror functionality would allow for very large-scale, low-cost mirror solutions. Here, we present both a solution framework as well as preliminary modeling results to demonstrate feasibility for a reflective ferrofluid, magnetically-actuated approach. We propose reflective ferrofluid development and optimization as well as manufacturing of a magnetically permeable paraboloid shell with surface wicking structure and electromagnetic coil arrays to deliver required wavefront performance and maintain fluid stability. We share our initial model and small-scale test results with baseline ferrofluid, wicking structure, and actuation inputs to demonstrate feasibility and describe our plans for a 50 cm mirror build in the near future.
