- Type B Past Week Summary
There were multiple issues with the dummy BS flag/prism gluing klog. The sapphire prisms will need to be removed and reapplied. Hirose-san is going to organize this. He wants to try the cup that had been made for the PR2 on the actual PR2 and then see if a new cup is needed for the BS (considering the different radius).
- Hirata-san added the optical layout information to the BS Inventor assembly. He requested tank information from Mirapro so he can continue to do SR2/3/M.
- Fabian finished the IM assembly and started on the IRM and RM. Some of the IRM panels had been improperly wrapped and really should be re-cleaned. The MPC (multi-purpose cube) on the RM will need some rework.
- Mark scheduled a review for Thursday 6/16.
- Type B ongoing issues
- Wires
- Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco.
- OSEMs
- Feedthrough Adapters
- Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote.
- Can we make SR wire breakers bigger?
- Fukushima-san will start on machining test soon (as of 5/27).
- Not enough crane height problem (Hirata, Saito) - no action since last week
- Installation stuff
- Crane scale - quote received
- Work platforms - RECEIVED
- Ballast masses for payload
- Initial batch received - ordered extra smaller ones to allow for adjustments.
- Lower breadboard stuff
- Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
- Breadboard springs (in manufacture, expected end of July)
- Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order.
- Clean bag - RECEIVED.
