| * Mark and Fabian went to Kashiwa to clean up glue residue on the dummy BS and do a fit/function test of Tatsumi-san's modified tooling. * Most of the remaining glue came off with soaking in acetone, but there is still some in the machining grooves in the Al surface. Probably more work is required. * A set of cleanroom shoes borrowed from the ATC disintegrated when worn (the plastic had perished from age), which put small pieces of foam all over the floor in Hirose-san's cleanroom and required a lot of clean-up with a sticky roller! Cleanroom suits and shoes for use by Type B team at Mitaka/Kashiwa have been ordered, but will take another week to arrive. * The flag holding parts are now much easier to place and remove, much reducing the risk of breaking flags after gluing. * The sapphire and metal prisms from both the first BS gluing and the PR3 hanging test mirror were brought back to Mitaka for ultrasonic cleaning to remove glue, so they can be reused. * Hirata-san found the SR versions of the screws for immobilizing the IM and IRM. These fit much better than the BS ones (despite being the same design) and will be used for the BS. |
* 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. * 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. * 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. * 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 even after the dummy optic and RM have been hung, so it should not delay work. |

- 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.
- 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.
- 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.
- 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 even after the dummy optic and RM have been hung, so it should not delay work.
- Type B ongoing issues
- OSEMs
Akutsu-san is working to get wide-mouth OSEMs (2 assembled; another few were assembled and a batch of 7 were washed.
- 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).
Longer cables for BF->PI and SF->PI.
- Connectors RECEIVED, cables being made.
- SR machining test NEARLY DONE. The part looks good and will be used but the ones for SR3 and SRM will be made from scratch.
