With Rishabh Bajpai, Shingo Fujii

The 2 shutters were installed. XPcal is now available again.

We installed a beam shutter just before AOM for path 1.
Operation checks (shutter OPEN/CLOSE check, kept close for over 1 h, kept open for over 1 h) beam shape check at Tx module, and output power check were performed.
We could not see any problem.

Because the shutter we installed today is home-made one, we need to replace it in the future.
