Plan: Tower assembly with Pb-210 source and Am-241 source mounted above DIB2.
| 1100 | Install upper IVC |
|---|---|
| 1130 | Clean EBox feedthroughs. |
| 1230 | Attach stripline heatsink at IVC ceiling. This time we put an additional crinkled up piece of foil in the tube against the L-shaped heatsink piece. As last time we put foil tape over the large hole in the bottom, taped to IVC ceiling (gappy enough to allow gas flow through hole and from dead-end screw holes) |
| Missing one screw for heatsink compression onto striplines. (0x80 3/8“ stainless flathead screw). We found this screw afterward. We will put it back next time. | |
| 1300 | Installed MC spool |
| 1430 | Installed lower 100 mK can (12 in*lb torque on screws) |
| 1500 | Assembled source holder with Pb-210 source and Am-241 source mounted above DIB2. |
| 1600 | Attempted to attach 30 mK can, applying standard 12 in*lb torque, but unfortunately damaged the threads in some of the holes in the spool. We used too-short screws (should have been M3-12, i.e. 12 mm long) so the screw was only in contact with a few threads at the bottom, and it ripped through them. |
