We’ve made some major progress this week with the assembly, pump-down, and bake out of the new 2DMOT chamber for 6Li and 7Li.
There are no indications of leaks so far with the blanked-off chamber baking at 250 C. If things still look good tomorrow, we’ll we’ll heat most of the chamber (especially the appendages that will house the lithium vapor sources) to >400 C to drive hydrogen out of the chamber walls.
