Accelerator Code Workshop Builds Momentum

The second annual Accelerator Code Workshop took place at SLAC last week. More than 35 participants from institutions around the world gathered to learn about a software suite known as Advanced Computational Electromagnetics 3-D Parallel, or ACE3P.

"ACE3P is widely known for its advanced capabilities," said Kwok Ko, head of the Advanced Computations Group at SLAC, which organized the workshop. "It's unique in that it's the only 3-D parallel electromagnetic code suite focused on accelerator applications."

The development of ACE3P started at SLAC about 15 years ago, according to Ko, with support from the Department of Energy's Scientific Discovery through Advanced Computing program. The software provides a more accurate and efficient way to design accelerator cavities and has been used to model the PEP-II and Linac Coherent Light Source accelerator cavities at SLAC, Project X, a proposed high-intensity proton accelerator at Fermilab, and a host of other accelerators worldwide.

A major goal of last week's workshop was to demonstrate the capabilities of the software so that accelerator physicists could take the knowledge back to their home institutions. Sessions covered the various modules of ACE3P and emphasized its use on parallel computing systems, such as those at the Lawrence Berkeley and Oak Ridge national laboratories. Users can log on to these systems and request time allocations to use the code suite for their applications.

Interest in the code and its capabilities continues to grow as more accelerator facilities are realized. In its second year, the workshop hosted twice as many participants as last year, a trend that Ko said he hopes will continue. 

Colloquium Today: Experiences of a Physicist in the United States Congress

This year's Monday SLAC colloquium series begins this afternoon with a talk from physicist and U.S. Representative Bill Foster. After a 25 year career in high-energy and accelerator physics, Foster ran for Congress for the Illinois 14th district in 2008, and has twice been elected to represent this diverse district. In today's talk, Foster will highlight some of his successes and frustrations in Congress, and offer his suggestions on how scientists can help shape good policy and how their skills can be applied to national opportunities and challenges, in "Another kind of Many-Body Problem—Experiences of a Physicist in the United States Congress."

Foster received his bachelor's degree in physics from the University of Wisconsin-Madison in 1975 and his Ph.D. in physics from Harvard University in 1983. He has been elected a fellow of the American Physical Society, received the Rossi Prize for Cosmic Ray Physics for the discovery of the neutrino burst from Supernova SN1987a, received the Particle Accelerator Technology Prize from the Institute of Electrical and Electronic Engineers, and was awarded an Energy Conservation award from the U.S. Department of Energy for his invention and application of permanent magnets for Fermilab's accelerators. He is currently serving in his second term of office. In a nationally watched race, Representative Foster won a special election in March 2008 to complete the term of former Republican Speaker of the House Dennis Hastert. In addition to being a bellwether for races to come, this win earned him the distinction of being the first Democrat to represent the 14th District since the 1970s. Foster followed up his March victory with another 16-point win in November 2008, and was sworn-in on January 3, 2009.

Refreshments will begin at 3:45 p.m., followed by Foster's talk at 4:15 p.m. in Panofsky Auditorium. The colloquium is free and open to all.

Next Monday, Ben Lenail, Distinguished Visiting Scholar at Media X at Stanford University, will present "Home Energy Management: Smart Grid Meets the Internet."
