Today we completed the installation of the vibration isolation system needed to suspend the filter cavity input mirror in the NM2 vacuum tank.

Such a system is composed by (from bottom to top):

1. A baseplate (see picture 1)
2. A three layer stack made of rubber and metal blocks (see picture 2)
3. A top-plate
4. A double pendulum system

In picture 3 the empty bottom of the vacuum tank is showed while in picture 4 the complete system can be seen.

Some test of vibration isolation are planned for the next days.
