1 STREGA Start up Meeting IGR - Geppo Cagnoli EGO – Cascina – 12 th May 2004

2 2 M1 – Advanced Materials for Mirror Substrates The thermal and loss properties of Silica at low temperature are not very good Sapphire is much better but it is dominated by thermoelastic noise IGR has proposed to use Si for substrates Sheila Hz

3 3 M1 – Advanced Materials for Mirror Substrates Meas. at room T on Si and CaF2 Meas. at low T on Si and CaF2 Investigation on the doping effect on Si Investigation on silicate bonding at low T Optical measurements on Si and CaF2 Prototypes Writing report IGR ON GOING ACTIVITIES IGR FUTURE ACTIVITIES

4 4 M1 – Advanced Materials for Mirror Substrates 2 CRYOSTATS 40X30 cm

5 5 M1 – Advanced Materials for Mirror Substrates IGR collaborates with Stanford on the M1 activities

6 6 M5 – Innovative Materials for Ad. Det. Suspensions Extend the experience of GEO600 from silica to silicon monolithic suspensions Silicon ribbons Silicon cantilever blades Silicate bonding

7 7 M5 – Innovative Materials for Ad. Det. Suspensions Measurements on Si, YAG, Mo, Ru fibres Production of monocrystalline fibres Measurements on monocrystalline fibres Local cooling of monocrystalline fibres Prototypes Writing report IGR ON GOING ACTIVITIES IGR FUTURE ACTIVITIES IGR POSSIBLE ACTIVITIES IGR collaborates with Stanford on the M5 activities
