Today at approximately 1PM, LCLS achieved its project completion (CD-4) milestone of delivering first photons to the Far Experimental Hall. This is a tremendous day for SLAC! I congratulate all of you who have worked so hard to make this happen. Above all, I want to congratulate and thank John Galayda for delivering this wonderful machine on time, on budget and with outstanding performance!
Well done, folks! This was one tough beast to construct, especially with such tight tolerances. It is an amazing accomplishment.
