• Announcement :

F2F presentations authorlist soon next meeting in January 15th

• Improvement of coating measurement apparatus :

Presented at JPS last week Designed and manufactured electrodes to reduce cross-talk between actuator and transducer In future, planning to test different geometries

• Coating measurement :

Sato-san will present his Master thesis at December F2F He leakage was solved which will improve the temperature resolution of new NAOJ coating measurement

• Parametric instabilities :

Otsuka-san will present his Master thesis at December F2F Onsite measurements at 80K match simulation within 300 Hz SIS simulation and theoretical estimation of RTL are now matching Computed PI at 1.3MW arm power and investigated sensing and mitigation using PCal beam
