Uraguchi, Tamori, Nakada, K. Tanaka,  and Akutsu in the afternoon

We took out the BRT-Y from the EYT chamber along with the fixed table. On th BRT, three "main" optic parts were able to be covered by the original covers, but it was not possible for an optic as there were not enough space around the footprint of the optic. Those covers were originally used when the BRT was transported from Mitaka (1.2 years ago...), but additional optical parts have been installed already, so the situation has changed.

The picked-up BRT-Y + the fixed table has been located at the side of the EYT chamber. Under the fixed table, we put two carriages.

We also pushed the metal shelf in the clean booth to the other side so that the sufficient space for the BRT-Y was able to be made.
