* Type B Past Week Summary * Fabian worked on IM and dummy BS assembly: [[https://photos.google.com/share/AF1QipMNVSExyP3TuyhK4s_VD-ARDlNoCPCf13ZDbHUlwOw14AKgj4XUe0vYg27dQ12icQ?key=SjJ0dXJ1bjN2OGVCN3d6RnoySEtFSjVJUmVwSlZR|photos1]], [[https://photos.google.com/share/AF1QipPQdoB5vYN1VcD32TkA4QSGldODvKRwiT5h-m122ahSpWmFyyrO5MX-9ajL1LeRIg?key=VFFuUVktcEtlMURQUldhZUlRcGFhbzNDeU5IN3NB|photos2]] * A hole in a picomotor holder was too small. ATC staff solved this isue quickly and Hirata-san cleaned the piece. * Some ballast discs for the dummy optic were dirty (seen by visual inspection). Hirata-san cleaned them. * Some arrows were cleaned from the mirrors for the dummy optic. * Hirata-san worked on checking Mirapro's assembly frame design - some minor issues with rail system found. * Hirata-san measured another filter. * Hirata-san washed a large batch of parts. * All parts for gluing of dummy BS are in hand. We arranged with Tatsumi-san to glue magnets at Mitaka on 6/6, glue flags at Kashiwa on 6/8, and inspect bonds and bring dummy BS back to Mitaka 6/13. * Mark worked on solutions to allow a [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeB/dummyBS|larger mirror on dummy BS]]. After discussions with Simon and Akutsu-san we decided to go with a stainless steel plate solution. The gluing can go ahead and we can attach the plates later. * Mark worked on list of items for purchase in FY2016. * Mark worked more on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235 BS Assembly Procedure]] ([[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|Draft on OneDrive]]) |

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.
- We powered down the BS, SR3 and SR2 electronics in preparation for the power outage.
