Mirror Support
The Mirror is supported through one
hole in the back where a dowel
is inserted.
The Mirror is falling: the dowel is
touching the mirror not in the barycenter
Actuating ribbon works against g and gives
vertical axis alignment
A second actuating ribbon at 90 deg gives
the horizontal axis alignment
Piezo motors are used to pull the ribbons
System heavily tested in Lab in Firenze

In this scenario the RICH could only be used if there is a window to prolong the TR in 2013 !
Conclusions
• Lot of progress on many items of RICH
• Vessel production (CERN responsibility)
delayed
• Mirror support system to be finalized
• The RICH is on the critical path for september
