Subject: Vacuum Leak Test 
Leak tested the worst flanges on the chamber after moving it and after bake 6. The 6 inch flange connected to the 8 inch reducing nipple is now leaking at 1.5 e-9, previously at 4 e-9. The 8 inch flange connected to the turbo pump is now leaking at 1.9 e-9, previously at 3 e-9. This means that the baking most likely improved the seals on these flanges and a hotter bake might fix the leaks for good.
