Following the approval of the ET Design Study:
Definition of tasks and tasks responsibles
together with involved groups
Kick-off meeting of the WP2 activity
Periodic (bimonthly?quarterly?) meetings
Encourage exchanges and coordination between
The involved groups and with other groups
in the Science Team
The Prototype of Cryogenic Payload
Marionette hosting the central insert made of silicon (at present the central insert is made of Al)
We have designed and built a cryogenic payload scaled 1:3.5 compared to the VIRGO standard
Electromagnetic actuators like the Virgo mirrors lateral ones (macor support, copper wire kapton insulated)
Next steps
Improve the vibration reduction scheme
To modify the sensing scheme to improve the noise floor at closed loop to the control of the horizontal degrees of freedom ;
Full scale cryogenic payload (with silicon)
Test a full scale silicon mirror at cryogenic temperature in the EGO cryostat in Cascina, Virgo Site;
To define in a realistic way the refrigeration procedure
The properties of the full scale silicon mirror.
