| * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]]) * Hung dummy optic and set pitch. * Prepared RM for hanging (adding OSEMs etc). One OSEM (#24) had wobbly leads and was brought back to Mitaka for rework. * Placed vacuum feedthroughs on assembly frame and cleaned initial batch (4) of D-Sub cables. * Decided position of BS rack with Miyakawa-san. * Measured various maraging rods and the rod holders on the SF. * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety. |
* 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). |

| * Made new 3D models of the maraging rods for PRx and SRx * Made new collet design for PRx and SRx (3D and 2D). * Made new IM flag design for PRx and SRx (3D and 2D). * Washed lots of Type A BF parts and OSEM parts. * Cleaned the BS BF-IM maraging rod and organized the rest of the stock of rods. * Measured some BF part dimensions. * Pre-assembled parts for BFs. |
* 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. |

| * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE. | * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing. |
