Preparation visit before Run6

15-17 May 2013: cooling down
18 May 2013: check resonances in a dark configuration and end the preparation as soon as it is ready. The cryostat stays cold until the observational run 6 in June.
Alessandro Monfardini, Martino Calvo and Nello D'Addabbo come by car from Grenoble.
