Keerthi found and fixed a couple more vacuum leaks last night. Present vacuum at IOS:IG1 = 4.4e-7 Torr. Electrical and water services installation in progress right now.

Later... Most of the services installed. Water tested: mostly OK, but persistent leaks on fiddly source body seals. Let Keerthi adjust these tomorrow. Power supplies wiring mostly done. A couple of source body connections await, plus primary power work by electricians. All in all, it's taking shape.
