At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun): * We solved the problem with the OSEMs: cables had been plugged into the confusingly named "PD current monitor" outputs (actually LED current monitors), not the "OSEM outputs". * We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power. * We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll. * We aligned the IRM to the IM and set the OSEMs to mid-range. * We added ballast to the BF. * We changed the receptacles for the SF-BF rod. The low receptacle did not fit properly into the BF keystone and Hirata-san had to file it. * We fixed a broken wire on the BF yaw pico, retested the pico and added the BF cap. * We cabled and tested the BF cap picos. * We lifted the BF and weighed and balanced it. * We installed the SF ring and brought in the SF. * We cabled the SF LVDT and did a quick test (not a full calibration). * We replaced non-vacuum compatible cables in the PI, removed various sticky labels and wiped it with ethanol. * We tried to hook the SF-BF rod but found the hole in the hex cable clamp was too small for the 8 mm rod head. We enlarged the hole but then found the PEEK pieces were too loose. We tried using foil, but then managed to lose a PEEK piece into the BF, so we will need to remove the cap of the BF to get it. |

==== Plan for week of 8/28 ==== Kamioka: Mark (except Tue), Ohishi-san, Fabian (except Tue), Enzo (except Tue), Hirata-san, Yoshioka-kun (Fri), Kozu-kun (Thu, Fri). * Fix/adjust IRM OSEMs. * Add BF cap; cable and test BF-1 and BF-2 picos. * Lift and weigh BF/IRM/IM/RM/BS; adjust ballast mass. * Crane in SF. * Suspend BF/IRM/IM/RM/BS. |
* We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box. * Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.) * Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.) * Enzo found nearly all in-vacuum cables. * Enzo and Shoda-san got several more loops closed on the BS. * Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4). * Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them. * Hirata-san worked on SR procurement. * Hirata-san worked with Mirapro to get the SRM LBB installed in the tank. ==== Plan for week of 12/4 ==== * Mark at Kamioka. * Fabian at f2f satellite meeting Mon, then Kamioka. * Enzo at f2f then Mitaka. * Hirata-san at Kamioka Mon-Thu, Mitaka Fri. * Kozu-kun Thu only. * Mirror gluing. * IM assembly and pico test. |
