Long Term Planning Theme at Annual Users' Meeting

"WHAT ARE THE DRIVING questions in high-energy physics for the next 25 years? What are the tools that will answer those questions?" These and other questions were posed by Peter Rosen, Associate Director in the DOE's Office of Science, during the annual SLUO Meeting in July. Over 200 users came to SLAC from around the world for a discussion about the science and politics of high energy physics (HEP). Speaking at the meeting, SLAC Director Jonathan Dorfan and Fermilab Director Michael Witherell expressed similar sentiments. Dorfan suggested that a different planning model is needed for the new challenges facing big science. "Previously we looked at a next generation machine and we endorsed that one s facility. It would be much better for the field if we which is intended to provide an update to the HEPAP looked 20-30 years ahead and developed a roadmap for subpanel. SLUO Chairman Ray Frey showed the future based on physics themes, not an emphasis transparenciesfrom Fermilab's Chris Quigg, who was on a machine," said Dorfan. He added that such a unable to attend the meeting. roadmap must be "world-based" since HEP is a global According to Dorfan, the near future will see data enterprise. "Scarce resources of money and people from several machines that will test the veracity of the necessitate a more international collaboration. We Standard Model, but he believes we have to be able to cannot risk regionalism." use those machines to a greater advantage. Among the According to Witherell, "There are exciting new machines are the B Factory at SLAC and the Tevatron results ahead in CP violation, dark matter and neutrino at Fermilab. mass, but I am concerned about the health of the field Fred Gilman, chair of the High Energy Physics since our base funding is down." Witherell said that Advisory Panel (HEPAP), also spoke at the Users' the HEP field needs to concentrate on the big physics Meeting on the "White Paper Process." He was charged questions of the future and what facilities are needed. by Peter Rosen with revising the 1998 HEPAP report to A major problem continues to be that current facilities reflect the changes in the field. "The landscape has are not being used to their utmost because of budget changed. PEP-II is in operation at SLAC and the Main constraints. Injector at Fermi is moving ahead. But we have had two very tight budget years below the constant level of a(1) funding, and that means we have to do a reassessment," 0 0 said Gilman. The White Paper will be a step along the way for the next HEPAP subpanel meeting in 2001 and will also provide input for the meeting at Snowmass in 2001. The report will cover the operations of facilities O0o now in use, frontier facilities worldwide, and the next 0o To steps for each.

In comparing the relative merits of a linear collider with the large hadron collider, that are being discussed and the international prospects Colby came to this conclusion: "The LHC will sight for such projects. the beast, and the linear collider will tell us what Another major reason for updating the 1998 species it is."

"With competing fields like of which supported the idea of an electron-based genomics and nanotechnology, we need a coherent linear collider.

He then expressed some of the plan. arguments that should be delivered to Congress. "Users are essential to the process and First, Rosen said that the study of matter focuses collaboration is crucial," said Dorfan. He added that on the deepest level of understanding of the universe. the lessons learned from the past show that science In looking at the past 50 years, there have been major has benefited from the combined strength of electron advances in science, technology and sociology that we and proton machines.

He concluded with the statement and this synergy is an important reason for changing that physics has made major contributions to other the paradigm from a short-term machine-based focus fields of science, such as computers, cosmology and to a 20-30 year long term focus on the physics. "We're medical accelerators. really looking forward to this planning process and Physics talks at the Users' meeting covered a the White Paper," said Dorfan.
