* Type B Past Week Summary * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka: * Hung RM. * Did permanent routing of RM OSEM cables to IM. * Did temporary routing of RM OSEM in-vacuum cables to flange (4 channels). * Did semi-permanent routing of all OSEM external cables to satellite amps (10 channels) * Did temporary routing of RM OSEMs to PR2 rack (4 channels). * Took data with geophones connected but immobilized and then stored geophones in boxes. * Tested signals from first satellite amp getting to digital system. * Weighed mirror box. * Did fit check of flag holders for stub flags. Very minor adjustments will be needed. * Covered everything in preparation for modifications to clean booth roof (9/20-21). * Hirata-san: * Finished 3D CAD of SR2 and SR3 in tanks, with optical layout included. * Started 3D CAD for SRM. * Checked flag design. * Assembled a bottom filter (ongoing). * Cleaned maraging rods. * Type B ongoing issues * Longer term to-do list * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing. * Part "disk security" top has to be modified - screw positions do not match. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING * Lower breadboard installation to be incorporated into the procedure document. * Work on BS simulation (Fabian) * Do BS Simulink model (Mark, Kokeyama) * Do 2D drawings of SR2 parts (Hirata) * Redesign SRx IM wire clamps for larger prisms, remachined RMs * Order SRM/PRM parts (Hirata/Shoda) * Order SRx fasteners (Hirata) |
=== Type B (Mark) === ==== Past week report ==== 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 LED current monitor outputs, not the PD 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 IM |

==== 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. ==== Plan for week of 9/4 ==== * Install SF cap; route cables. * Lift and weigh SF/BF/IRM/IM/RM/BS. * Adjust SF ballast. ==== Vacation Info ==== Mark: TBD Mid-Oct |

Type B (Mark)
Past week report
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 LED current monitor outputs, not the PD 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 IM
