| * Type B Past Week Summary * Fabian took photos of the cleanroom in the ATC. * Hirata-san ordered wire for the BS. * Fabian weighed the masses that he'd been constructing in the cleanroom and found a 600 g discrepancy from the Inventor. * Hirata-san ordered a medium-capacity scale to help check the masses of the parts. * Type B ongoing issues * OSEMs * Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test ongoing. * Lower breadboard stuff * Installation to be incorporated into the procedure document.

=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun): * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables. * We hung the RM and set its pitch. * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system. * We installed the bottom section of the security structure to protect the RM/BS. * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses. * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame. * We brought in the new BF. * We installed the BF-IRM rods and IRM top plate. * We reinstalled the IM flags and other items that had been taken off to use the winch system. * We hooked the BF-IM rod (with hex cable clamp).

Type B (Mark)
Past week report
At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
- We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables.
- We hung the RM and set its pitch.
- We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system.
- We installed the bottom section of the security structure to protect the RM/BS.
- We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses.
- We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame.
- We brought in the new BF.
- We installed the BF-IRM rods and IRM top plate.
- We reinstalled the IM flags and other items that had been taken off to use the winch system.
- We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.)
- We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT).
Plan for week of 8/14
