Description
This work originates from the aim of reducing the height of the 17 m suspension chain considered in the ET 2011 Conceptual Design Report and its 2020 Update. The presentation focuses on the current state of design and modelling of a candidate solution integrating both an inverted pendulum and an active platform. This key feature allows reducing the height of the seismic attenuation chain, while satisfying the requirements in terms of residual longitudinal motion of the test-mass below the ET-LF design sensitivity reaching $7.45e{-24}$ Hz$^{-1/2}$ at 3 Hz.
