 +==== Day 2026-04-09 (q3k, Rob, guest, leah) ====
 +
 +Reconnected cooling system.
 +
 +Replaced vacuum pump with Edwards pump from Wedel haul. Gets to a decent vacuum, but can't tell if there's still a leak in the column or whether it's outgassing after being at atmosphere for a while.
 +
 +While imaging loud 'click' happened, image turned black and there's no filament current. Checking if it's a burned filament or something else.
 +
 +==== Day 2026-03-01 (rahix) ====
 +Tried connecting ''FRONT'', ''BACK1'', and ''BACK2'' all together using pneumatic T-couplers.  It doesn't work, the weight of the column is too much off the side, meaning one bellow stays in contact with the bottom while the diagonally opposite one is at the top limit.
 +
 +Reverted back to the previous state with three separate valves.
 +==== Day 2026-02-14 (rahix) ====
 +Fixed the very leaky tire valves of the isolation system. We now have proper pneumatic isolation valves on all three tubes instead.  They are labelled now:

 +The back bellows are labelled ''BACK1'' and ''BACK2'' for clarity:
