Tomorrow we bake

Milly is coming along nicely.

I believe we’re over the vacuum difficulties. She’s buzzing along at a nice deep vacuum in the SPEC, INT, and GUN chambers. Last night the computer finally booted up without the dreaded CHECK VACUUM alert.

[Finally, a new and excitingly different error message!

Next up will be an extended 30 hour bake session to try to revive the emitter. I don’t trust her to run the heater unattended, so I’ll be staying over at the shop to keep an eye on things.

[This is the specimen chamber pressure. The gun is all the way down to 5e-11 kPa, pre-bake!

Keep your fingers crossed. With any luck I might have some images to post on Sunday evening!
