We are pleased to announce a small in-person workshop with the focus on low-frequency controls and inter-platform motion for the Einstein Telescope (ET-LF). We plan to improve our understanding in these areas, interaction between Work Packages (especially exchange of knowledge between Suspension and Controls), and work out the procedure to derive realistic requirements for the Einstein Telescope. Some time will also be dedicated to reviewing and improving the modelling tools themselves, organized as a "Hackathon" parallel session.
