- Type B Past Week Summary
- Akutsu-san provided a set of cleanroom gear (shoes only slightly too tight!) for use by Mark this week. And Sakamoto-san sent another set from Kamioka to Kashiwa.
- Fabian did a fit test of the winches onto the IM.
- The RM, IM and IRM were weighed, and wrapped/packed for shipment to Kamioka.
- Mark made a checklist of all the parts of the BS mirror box and gluing jig, to help with collecting the parts from Kashiwa.
- Fabian designed an extra 600 g of trim masses for the IM and Hirata-san made drawings and ordered them. The design allows for the masses to be added to the IM even after it has been placed in the assembly frame and the dummy optic and RM have been hung, so it should not delay work.
- Mark worked on the schedule, making the next few weeks more realistic and incorporating the new plan for the SR RMs (the test will be used for SR2 but two more will be made from scratch next financial year).
- Fabian worked on the payload assembly procedure.
- Hirata-san washed 7 OSEMs for Akutsu-san, and various other parts for Yamamoto-san of ICRR.
- Hirata-san removed the remaining glue from the BS primary and secondary prisms, as well as the prisms removed from the PR hanging test mirror. (The small sapphire prisms for the PR were not intended to be reused and one had already broken at Kashiwa, but the metal PR secondaries can and will be used again.)
