Summary
Following ID 1649 we start the implementation of the South cavity path.
Some optics has been placed along the path.

Conclusions 
A quick beam profile measurement and the implementation of the BB EOM
is the next step.
 

Things done:

• Optics as shown in the setup have been placed;
• References of the beam along the path have been aligned  (Those should be kept in place)

Notes:

• The FI is mounted on a base which brings it NOT at 3" height; Two steering mirrors have been used to overcome this issue;
• There is a second beam coming from the FI; I did not have a chance to play with it, but Andrew did and the origin of that is not totally understood;
