We received back the source this morning. First order of business was to take some EOB scans. See earlier entry. Then we shut down the source and opened the cage. Water leaks fixed. We had agreed with ICR to let them go for the sake of continuous beam to our users, so that we could avoid switching off the source. All done. There is a little weeping on one or two of the source body screws, as expected. As a practical matter, we aren't going to fix these.

Research-grade helium gas and lines hooked up today. Metering valve installed inline. Lines are pumping now. One-pass helium purge done.

Note: We had first beam today from the I3 development H- ion source, presently set up in the CRM on a borrowed test stand. Yes!
