On Wednesday 20th, after the opening of the upper part of the SR tower by VAC team, we proceeded with the integration of the  inertial platform prototype.

The platform has been installed on the bottom ring of the suspensions  and consists of an aluminium plate supporting 1 vertical accelerometer, 2 horizontal accelerometers, a 2-axes (tx and ty) gyroscope. Also the in-vacuum and air side cables were installed, and the signals were succesfully checked  (the relevant electronics was installed during the previous testing phase).
