LCLS Groundbreaking Celebration

LCLS excavation proceeds in advance of the groundbreaking ceremony to be held October 20 at 10 am. (Click on image for larger version.)

Everyone is invited to celebrate the beginning of a new era at SLAC!

On October 20th, from 10 a.m. to 12 p.m., SLAC will celebrate the groundbreaking of the Linac Coherent Light Source (LCLS), and you are invited to join the festivities. We are delighted to announce that Raymond Orbach, Department of Energy Under Secretary of Science, will host the occasion. Congress members Mike Honda and Zoe Lofgren, as well as other VIPs from Washington D.C. and California, will also attend. Come see LCLS Project Director John Galayda personally operate an excavator to remove the first bucket of earth from the site.

Crews will erect a special facility for this multi-media event in the parking lot of the Collider Hall (building 750) on PEP Ring Road, directly adjacent to the construction site. Transportation to and from the ceremony will be provided for everyone.

Watch this space in the next few days for more information about this exciting event—this is an ideal chance for you to see firsthand the LCLS site and the excavation progress made so far. Come join us for refreshments, music and entertainment, at SLAC’s official LCLS groundbreaking.

SLAC's ILC L-Band R&D Program

End Station B these days is the site of the largest International Linear Collider R&D effort at SLAC, the development of the L-band (1.3 GHz) radio frequency (RF) power source.

The L-Band R&D program will have three stages. In the first stage, a 13 MW modulator on-loan from SNS was installed in End Station B to power a commercial 5 MW klystron. This RF station will be used to test waveguide components for an improved ILC RF distribution system and to test a normal conducting 5-cell structure for the positron capture system that is being fabricated by the Klystron Department. It will also power a stand for studying and RF processing power couplers for the superconducting cavities. The modulator and 5 MW klystron are operational and the installation of the other elements is underway. These systems should be completed by mid-2007.

In the second stage, two new 15 MW modulators will be installed in End Station B: one developed by Diversified Technologies through SBIR funding, and the other an innovative Marx Generator design being developed by a team led by Greg Leyh of the SLAC CPE group. These modulators will power two 10 MW multi-beam klystrons that are prototypes for the ILC baseline RF source. The civil construction for the new modulators will involve removing the shielding wall between the target room and the rest of End Station B. The modulators will be installed in early in 2007 and the two 10 MW RF stations should be fully operational by the end of 2007.

The third stage of the R&D program will be to select the RF power system design for the ILC from the different modulators, klystrons, and RF distribution systems tested. Then six ILC spec RF units would be built and operated for lifetime testing and further pre-production engineering improvements. These stations would be installed in either End Station A or the Klystron Test Lab by late 2009.

Stanford President Announces New University Initiatives

Stanford University President John L. Hennessy announced Tuesday the launch of an ambitious series of educational and research initiatives called "The Stanford Challenge." The goal of this undertaking is to place Stanford University at the forefront of the search for knowledge and solutions to the challenges facing society in the 21st century.

Included among these efforts are initiatives in undergraduate and graduate education; human health; the environment; multi-disciplinary research and international relations.

According to President Hennessy, the goal of The Stanford Challenge "is nothing short of building a university for the 21st century and beyond: A university that will better serve the world through the quality, impact, and vision of its research, and through the new generation of leaders it will produce."
