Participants: Matteo, Haoyu, HYamamoto, Abe, KYamamoto, Marc, Marco, Katsuki, Simon, Aso, Michimura

=== Next meeting ===
2021 November 24, 15:00 - 16:00

== Minutes ==
 1. Report from KYamamoto-san about Q measurement at cryo temperature
  * new contact point (from 2mm to 1mm) for disk suspension seems promising but has some stability issue -> new contact point with 1.5mm will be tested
  * measured Q for 20(x2) layer stack is 8e-4 which is larger than expected -> the impact in BRSE sensitivity seems to be <2%, impact in DRSE will be investigated by MIF
 1. Report from Simon about birefringence paper
  * impact of input beam direction is being investigated -> does not seems to impact in the measurement at the first order
  * for future works, the impact of c-axis direction will be evaluated
 1. Report from Marc on measurements
  * currently measuring TAMA #1 sample (Shinkosha)
 1. Report from Haoyu on birefringence simulations (from TWE)
  * correct orientation angle of TWE maps has been obtained, computation with general model ongoing

== Agenda ==
 * various updates
 * AOB
