[Jenne Kiwamu Joe Osamu Steve Koji]
Yesterday (21st), we closed the BSC and the four testmass chambers.
We splitted the team into three.
- Wiping team (Jenne/Kiwamu)
- Suspension team (Osamu/Koji)
- Door closing team (Joe/Steve)
While the wiping team was working, the suspension team prepared the next suspension.
Once the mirror was wiped, the suspension team restored that suspension at the position of the markings on the table.
After the wipe of the first mirror, the wiping team got experienced and they were the fastest among the teams.
So the wiping team worked as the second suspension team when necessary.
All of us became the closing team after the last suspension has been restored.
We checked that we still have the Michelson fringes and the oplev pointings.
In total, the work was very efficient such that we only took four hours for the entire process.
We left the suspension marking on the optical tables because they are quite useful.
