Firing up the LCLS: Rhymes with "berzerk"
Saturday, December 13, 2008
2:50 pm Four and a half hours and many donuts later we are still waiting for the chance at a second shot. But the good news is the radiation physics guys have signed off on the repair of the BSOIC that quashed efforts earlier. There was some speculation that the safety folks would need more than a little time to resolve the issue, but those in the know say that the issue is resolved and that all that remains is another safety sweep. Should have shot two within the hour.
Also: turns out the betting pool relates specifically to getting the beam through the undulator hall. Since they haven't even gotten to the beginning of it yet, the first shot doesn't count. No wonder there's such uncertainty: the vacuum chamber in the UH is barely bigger than a drinking straw, and it's three football fields long. Alignment of the beam is no small feat. posted by Brad Plummer @ 2:50pm
