| | Status: warmup finished. All mixture in dump, fridge isolated. LN2 traps warm and pumped out. 1K Pot needle valve closed. Tower removed. |
| | Continuing fridge disassembly, in preparation for replacing striplines. Following guidelines from August 30. |
| 1120 | Middle IVC can removed. MC spool removed, after detaching thermometer wire - it was held in place with some teflon tape and one tabbed “bandaid” of kapton tape. |
| 1230 | 100mK can removed. Measured stripline length from bottom edge of bottom piece of heatsink at IVC ceiling to the upper edge of the connector: shortest stripline = 28.75 inches. (Longest is about 3“ longer.) |
| | Distance from bottom of lowest stripline baffle to top of IVC ceiling heatsink = 1 inch |
| 1240 | IVC ceiling stripline heatsink removed. Distance from bottom edge of lowest baffle to to upper edge of stripline connector, shortest stripline = 34.25 inches. |
| 1300 | Stripline end protectors and heatsink buckle removed. |
| 1425 | Upper IVC removed.
Stripline tube (wizard staff) removed: loosened the two compression rings at top, then gently lowered it through the fridge flange and all the baffles. When we got it out, noticed some zig-zag scratches near the top - we will want to try to polish the end, and protect it with tape as we did in the last installation. |
| 1445 | Remove end cap of E-box and disconnect stripline d-subs. There was not enough slack because the striplines were hanging freely - pushed them up from below for more slack, and wedged a screwdriver between a stripline baffle and a fridge baffle to hold them up. |
| 1500 | Remove rear E-box cap and disconnect from bellows. But I shouldn't have removed the cap - should leave this on. Pushed the stripline d-sub ends through the back and remove the e-box off of the fridge stand. |
| 1515 | Remove 2-belows-plus-t-connector tubing between e-box and stripline elbow, feed stripline d-subs through it and set tubing aside. Now we are ready to remove the striplines from the fridge. (No need to remove upper 100mK can or 600mK rod.) |
