Willkommen, New BaBar Leadership!

The BaBar Collaboration held its autumn collaboration meeting in Berlin, Germany last week. On Tuesday, the meeting's Collaboration Council ratified the fourth member of the new BaBar management team. With the fourth member in place, SLAC and the international BaBar Collaboration can now officially welcome the new team.

"The main focus of this management team is to make sure the collaboration is well positioned to get physics publications out," said BaBar's new spokesperson, Michael Roney. "The challenge is to have BaBar function effectively and with high efficiency, even though data taking stopped in 2008. This will ensure people can finish the work that we have started."

Roney takes on leadership of the new BaBar management group as Spokesperson Emeritus Francois Le Diberder steps down from his two years of service. Roney is a professor at the University of Victoria in Canada, and served as chairman of the Physics and Astronomy Department there until 2008, when he took over as BaBar's deputy physics analysis coordinator. For the past year he has served as BaBar's physics analysis coordinator, prior to taking on the mantle of spokesperson. Read more...

Congratulations, SPEAR:
20 Years as Dedicated Lightsource

Twenty years ago this month, SPEAR (the Stanford Positron-Electron Accelerating Ring) retired from the particle-smashing business and started a second career as SPEAR, an electron storage ring dedicated to the Stanford Synchrotron Radiation Lightsource (then the Stanford Synchrotron Radiation Laboratory). The dedication ceremony included the handing over of a symbolic SPEAR "key" by then-SLAC Director Burton Richter to Arthur Bienenstock, who was SSRL Director at the time.

SPEAR initially began operations in 1972, and it didn't take long for discoveries at the ring to revolutionize particle physics. In 1974 Richter discovered the J/psi particle, which led to confirmation of the existence of the charm quark, and in 1976 SLAC physicist Martin Perl found the tau lepton, the electron's heavier relative. But even while Richter and Perl were gathering their data and making their Nobel-winning discoveries, synchrotron radiation emitted by SPEAR's electron and positron beams was being put to good use by the Stanford Synchrotron Radiation Project, with five experimental stations sharing a beamline.

By 1977 the SSRP comprised two beamlines and nine experimental stations and traded in its "P" for an "L," becoming the Stanford Synchrotron Radiation Laboratory. Demand for synchrotron radiation continued to grow. The addition of an injector to SPEAR in 1990 meant that the ring was no longer dependent on the linac for electrons, and paved the way for the creation of a dedicated lightsource for SSRL.
