* 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). * 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) |
* Mark and Hirata-san at Mitaka * Gathered parts for cable making. * Mark and Hirata-san at Kamioka: * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame. * Installed two more LPCDs and the stepper motor driver in the PR2 rack. * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs). * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs. * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement. * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4). * Added extension to the IM pico cable for the BF yaw pico. * Made LVDT adapter cable. * Mark worked on schedule. |

- Gathered parts for cable making.
- Mark and Hirata-san at Kamioka:
- Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
- Installed two more LPCDs and the stepper motor driver in the PR2 rack.
- Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
- Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
- Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
- Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
- Added extension to the IM pico cable for the BF yaw pico.
- Made LVDT adapter cable.
- Mark worked on schedule.
