==== 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). |
==== Report for week of 2/19 ==== * We did TFs from the IM OSEMs. * We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap. * We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected. * Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF. * We added the AF crossbars and the section of the SS below the SF and craned in the SF. * We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range. |

Report for week of 2/19
- We did TFs from the IM OSEMs.
- We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap.
- We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected.
- Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF.
- We added the AF crossbars and the section of the SS below the SF and craned in the SF.
- We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range.
