  1. Q measurement of fundamental drum mode of ETMX done on Nov 3rd
    • 2.1 x 10^5 which is 1-2 order of magnitude smaller than expected
    • Q value could be limited by suspension dissipation
    • even if lower than expected should not impact on the system thermal noise
  2. Update from ARD: activity proceeding faster than expected, a small chip on barrel was discovered and will be investigated
  3. Report from KASI:
    • small sample delivery expected in few days
    • zygo interferometer tests ongoing, problem with polarization
  4. introduction of new characterization techniques for birefringence measurement by Marc (will be presented at FWG meeting on Nov 17th)
