At present, the PT01~04 output became stable. So this fluctuation comes from the unstability of the cryocon or wiring connection trouble due to yesterday's activity on the metal mesh? Ikeda-san and Yokozawa-kun, do you have any idea?

Actually, the fluctuation is sometimes so fast. It cannot be induced by thermal influence from the mesh area to the optical table.

On the other hand, PMC output oscillation continues.
