No leaks during a bakeout of up to 450 C, the base pressure with just the ion pumps is in the low 10-11 torr range, and the residual gas analyzer shows nothing but a little hydrogen left. I think we can call this a success.The outside of the chamber isn’t quite as aesthetically pleasing as it was, but the inside is very, very clean, and ready for installation of windows, and the lithium vapor sources. Next: move it to the main table and get ready to attach the main chamber.
