Building the LCLS: Weekly Update

From the Director: PPA Scores a Hat-Trick!I am not a sports fan, but I could not come up with another way to describe the achievements of the Directorate of Particle Physics and Astrophysics (PPA) this past week. First: The Gamma-Ray Large Area Space Telescope (GLAST) had its first science data run last week, taking four days of gamma ray observations as part of their turn-on plan for the instrument. While data plots will not be public until the first light celebration in early August (when a new name for GLAST will be announced), the collaboration members use adjectives like "spectacular," "beautiful" and "outstanding" to describe the data. As a Large Area Telescope team member, I have been privileged to see some of the early sky maps. They are truly gorgeous. From a only few days of data, the outstanding power of the instrument is evident and the tremendous science potential is clear. Second: Wednesday, BaBar announced the discovery of the ηb. For those of you who remember your quantum mechanics, this is the singlet state of the b anti-b quark bound state, analogous to the singlet ground state of the positronium atom. We have been looking for the ηb for 30 years, ever since the Upsilon resonances were first discovered. The analysis can only be described as a tour de force. Read more... |

Photographer Stanley Greenberg: Back at SLACTwo years ago, photographer Stanley Greenberg visited SLAC to explore an undeveloped idea he had for his next project. He was taking photographs of high energy physics laboratories, and had also been to Fermilab. Since that first visit to SLAC, Greenberg's idea has taken him all over America and halfway around the world. He returned to SLAC last week to take more photographs for what has become a very grand plan. Those earlier photos of SLAC, Fermilab and CERN helped Greenberg earn a grant from the Alfred P. Sloan Foundation to create a book focusing on high energy physics experiments. In the past two years, Greenberg has photographed
more than a dozen American labs, as well as CERN in Switzerland and DESY in Germany. Later this month he's heading to Japan to photograph KEK, Super-K, J-PARC and
the KamLAND Reactor Neutrino Experiment. In August he will visit
the Pierre Auger Observatory in Argentina. |
Yoji Totsuka Has Passed AwayFormer KEK Director General Yoji Totsuka, 66, died on Thursday, July 10, KEK has announced. Yoji is remembered for his contributions to the study of neutrinos, including foundational work with Kamiokande, a large water cerenkov detector which observed neutrinos from supernova SN1987, and the SuperKamiokande detector, which led to the discovery of atmospheric neutrino oscillation. Yoji joined KEK in 2002, and became the director general in April 2003. He received numerous awards including the Order of Culture of Japan, the Bruno Pontecorvo Prize in 2004 and the Franklin Institute Awards in 2007. Funeral services will take place in Tokyo on July 12. Word of the Week:
