Previous Day

* Lab in-personnel: Zach

IVC open. Mixture in dump. Warm LN2 Trap 1 clean. Clean tent erected at bottom of fridge. Deinstallation started, tower removed.
1500 Remove clean tent from bottom of fridge.
We plan to tighten the mixing chamber bolts. We will begin disassembly of the IVC, as was done on 2021 May.
1524 Remove bottom stripline heatsink. Requires 5.5mm crescent wrench and 2.5 mm Allen key. Put pieces in labeled bag. Detach stripline buckle from top of the lip at the bottom of the IVC middle can, leave hanging at end of striplines (it will stay there)
1545 Remove middle section of IVC. First loosen all screws. Remove all but two, leave those loosened to 1-2 mm. Insert screws into the two push-holes and tighten them down to break the indium seal. One person then holds the can while the other removes the last two screws, then carefully lower can and put on table on wipes, taking care not to scratch bottom o-ring surface.
1553 Remove 30mK can, which is attached with 6 brass screws
1618 Remove MC spool. Remove the center 10mm nut and 5 of the 7 screws. Then hold up the spool while removing the last two screws.
1427 Remove 100 mK can (6 stainless steel 2.5mm Allen-key bolts with washers)
1757 Using a 2.5mm Hex driver, tighten the stainless steel bolts on the bottom plate of the MC.

Earlier, this step was done with the full IVC open state. last time
