Next meeting

2023 ?? ??, 1?:00 - 1?:00

Minutes

  1. Paper on coating (Mori, Nakayama): Ti doped (LIGO) and undoped (KAGRA) SiO2-Tantala stacks

    • coating thermal noise seems higher than expected value
    • internal review by coauthors being done at the moment
    • will be circulated to MIR subgroup in the next weeks
  2. Planned presentation of the measurements contained in the paper at the next LVK
  3. Measurement of Q-value for KAGRA sapphire mirrors
    • CARM-DARM as readout sensors, magnets as actuators
    • T= 80K for ETMX and T=250K for all the others
    • all Q value are between 1e4 to 1e5, seems low compared to expected value of 1e8
