1. The rails of the hoisting system for the microtower have been installed on the ceiling.
2. The plate covering the concrete floor has been put in place.
3. A temporary hoisting system has been used to put the microtower in the proper position.
4. The pillars for the optical breadboards hosting the local control system have been put in the proper position.
5. The pillar for the optical breadboard hosting the optical devices (optics, photodiodes, cameras) installed in transmission of the cavity has been put in the proper position.
So far, nothing has been anchored to the ground to allow the leveling and the fine positioning.
The central part of the microtower has not been installed to allow the installation of the payload. Therefore, the vacuum pipe was not connected.
The final hoisting system will be installed later.
