LCLS to Begin Construction

The Department of Energy (DOE) has approved the start of construction for the Linac Coherent Light Source (LCLS). This milestone gives LCLS full permission to break ground and start digging tunnels.

"Now the fun begins," says Director of LCLS Construction John Galayda. Construction ought to start by the end of July and conclude in 2008.

Galayda can list a "never-ending succession" of milestones to accomplish before then. The next major undertaking is the 2006-2007 shut-down, when the LCLS injector will be installed and the linear accelerator will be modified to produce high-current pulses. Galayda says he hopes to test the performance of the LCLS injector by January 2007, which will measure the quality of the Free Electron Laser's electron beam. If all goes according to plan, researchers should be able to begin experiments in 2009.

Colloquium Monday

BaBar: Searching for the Unexpected

On Monday, April 24, SLAC's Aaron Roodman will present the colloquium "BaBar: Searching for the Unexpected."

With over 300 million B-Bbar pairs delivered by the PEP-II B-factory, and over 200 publications, the Babar experiment has studied a broad range of B, charm, tau, and QCD topics. In fact, the physics at Babar is so wide-ranging that it threatens to overwhelm any summary. In this colloquium, Roodman will highlight research topics specifically selected for their potential to find a truly unexpected result. CP violation in rare B decays, leptonic B decays, and lepton-flavor violating tau decays each hold great promise for uncovering the unpredictable - study measurements, currently predicted results and possible avenues for surprise discoveries, now and into the future, will be described.

The colloquium will take place at 4:15 p.m. on Monday, April 24 in Panofsky Auditorium. All are invited to attend.

Stanford Scientific Magazine

(Image - Stanford Scientific Magazine)There are many science magazines around the world, but did you know that Stanford University has its own?

Stanford Scientific is Stanford's only student-led science magazine covering cutting-edge science, ethics, and policy news. The magazine comprises undergraduate and graduate students who share a passion for providing a forum for students to express their knowledge and perspectives on the implications of new scientific advances. The magazine also seeks to explore and report on new scientific discoveries and research-in-progress in the Stanford scientific community through interaction with faculty and research at the undergraduate and graduate levels.

Stanford Scientific was created in the spring of 2002 by a group of conscientious science students with the aim of bridging the disconnect between scientific discovery and the application, social impacts, ethical issues, and policies that result from new technologies. 

Stanford Scientific serves as a forum for students at the undergraduate and graduate levels to consider the implications of technology beyond the laboratory.  Read more...
