* 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)
Report for week of 9/10
- We finish the invacuum and in air cabling for SR2, but the in-vacuum cables for Geophones and F0 Yaw stepper motor are just temporary and will be replaced later once the suspension is inside the tank.
- We checked all the motors, like:
- the IM picos, BF picos.
- We checked the BF Stepper (Fishing rod), SF Stepper (SF Fishing rod), F0 Stepper (F0 Fishing rod).
- We debugged an issue with the IP LVDTs and discovered it was a broken interface card D1402829 in the LVDT driver. We made up a working chassis with the original two driver cards, so we didn't have to reset all the phases and gains.
- We reset the IP FRs to midrange.
- We added a basic set of arc weights and recentered the IP. We then adjusted the verticality of the security structure.
- We relocked the IP temporarily, unlocked the SF/... section and aligned the IM OSEMs.
