Big Breakthrough for LCLS

by Brad Plummer

This week, SLAC will mark another "first" for the Linac Coherent Light Source (LCLS) construction project. Tunneling crews have been mining for months through the sandy soil of SLAC, and this Wednesday morning, the road header excavating the Undulator Hall will break through into daylight.

You can witness this one-time-only event from the comfort and safety of your computer, as SLAC Communications brings you a live webcast from the site. Tune in Wednesday morning to watch online as the road header punches through the final inches of earth. Director of LCLS Construction John Galayda will deliver remarks shortly before the event.

More details will follow in the Wednesday edition of SLAC Today.

"First Light" for
LCLS Tunneling

Recent months have brought us a steady drumbeat of successes from the Linac Coherent Light Source (LCLS) project. The many teams from SLAC, Turner Construction Company and their contractors have worked incredibly hard to see that milestone after milestone is safely and efficiently met. This past April we witnessed "first electrons" from the LCLS laser and injector teams, and this week brings us another major milestone.

On Wednesday morning, mining crews excavating the Undulator Transport Hall will break through the final few feet of earth into daylight. After nearly three months and 560 feet of digging, the road header has made its way from the research yard, beneath the overlook hill and through to the other side.

You can watch Wednesday's road header break through on your computer via a live webcast, starting at about 9:00 a.m. Stay tuned to SLAC Today in the coming days for more details.

Although Wednesday's breakthrough is an important—and quite visible—milestone, much work yet remains before excavation is complete. Crews have been working double shifts for many weeks to expedite tunneling progress, and that level of effort will continue. Work on the access tunnel behind Building 750 (the Collider Hall) is progressing toward the underground site of the Far Experimental Hall, and won't be complete for several months.

The LCLS construction project is a very complex operation, and as always, safety has been a driving factor. I extend congratulations on behalf of all of SLAC for what has been a highly successful coordination effort between SLAC and Turner Construction Company to reach this point safely and on schedule.

Reminder: St. Lawrence String Quartet Performs

The Grammy-nominated St. Lawrence String Quartet, Stanford's Ensemble-in-Residence, will play three extraordinary lunch hours this week. As part of their annual Chamber Music Seminar, the Quartet will perform on Monday, June 25, Wednesday, June 27 and Friday, June 29 at 12:15 p.m. in Stanford's Dinkelspiel Auditorium. The one-hour performances are free and will feature different material each afternoon. More information...

DOE Global Science Gateway Now Open

from the DOE

The U.S. Department of Energy (DOE) and the British Library, along with eight other participating countries, recently opened an online global gateway to science information from 15 national portals. The gateway, WorldWideScience.org, gives citizens, researchers and anyone interested in science the capability to search science portals not easily accessible through popular search technology such as that deployed by Google, Yahoo! and many other commercial search engines.

Safety Firsts

by John Cornuelle

This is a test—when would you turn around and go back? You're in your car (not an SUV) with your spouse and two small children; it's night; you have no food, water, or survival gear; you have a long way to go; it's raining/snowing; you are driving up into the mountains; you may or may not be on the right road; there are no road signs; there is no cellular coverage in the mountains; there is no sign of life anywhere; there are no cars in front of or behind you; but you keep driving; if you got this far you totally fail.
