We confirmed the height of the breadboard (BB) in the OMMT/OMC chamber.
Measured distance between the floor level of OMMT chamber and the top of BB:
The measured height was consistent with the design one within the measurement precision.
The floor level of OMC was heigher than the OMMT one by 3mm.
[Takahashi, Ikeda]
We confirmed the height of the breadboard (BB) in the OMC chamber. We measured the distance between the floor level of the OMC chamber and the top of BB with the laser leveler. The BB top was (135.5-80=55.5mm) higher than the 1000mm point from the floor. This height (1055.5mm) was consistent with the last confirmation (1058-3=1055mm).
Could you please tell us when is the last measurement? before the Noto earthquake?
Please see the original report in 2019 (klog 9555).
