Firing up the LCLS: Two shots in the dark
Saturday, December 13, 2008
4:40 pm Ok so I was wrong... the tweaking continued immediately after parking the beam at the tune up dump, and took less than an hour. (The radiation physics group was scheduled to do a measurement sweep AFTER the beam went into the undulator hall.)
The betting pool is decided: Two shots. The winnner: Paul Emma, the man on the mouse. (Emma heads up the group responsible for commissioning the electron portion of the LCLS.) Two clicks. The control room erupted in applause. "I knew these guys were good, but... [laughs]," said John Galayda (director of LCLS construction). "This is story book." "The man knows his machine," said Jim Turner (project leader for today's shift in the control room). The first try made it only a quarter of the way down, much head shaking ensued. But with the second click, score. Truly an amazing feat. Very small needle, and the team managed to thread it in two tries. posted by Brad Plummer @ 4:40pm
