A View from NSF The Early Years of CESR David Berley University of Maryland May 31, 2008 Two Aspects of Cornell’s Success in the International Arena of Larger Laboratories Technical Innovation First Rate Management

MY Years at NSF –1974 – 1977 –1980 – 1993 (Cornell CESR) – My first recollection of CESR –Late 1974 or early 1975 After the J/ Ψ discovery ~Two-Year process of approval

J Particle PRL (1974) Ψ Particle PRL (1974) Four known vector mesons ρ, ω,Φ,J/Ψ. Were there others?

CESR Proposal IEEE Transactions on Nuclear Science, Vol. NS-24, No.3, June 1977 CESR - AN ELECTRON POSITRON COLLIDING BEAM FACILITY AT CORNELL M. Tigner Cornell University Ithaca, N.Y SCIENCE, VOL. 204, 18 MAY 1979 Proposal May 1975 Vernier Injection Resulted in a crucial reduction in cost.

1.Construct PEP e + e - facility at SLAC 2.Construct ISABELLE at Brookhaven 3.Support R&D for 1 TeV Fixed Target & Collider at Fermilab 4.8 GeV e + e - facility at Cornell not recommended in FY 1977 The HEPAP of 1974 also recommended PEP and ISABELLE for construction. Cornell and Fermilab embarked on vigorous R&D Programs

CESR approval waited until 1977 Two years before the Upsilon Discovery PRL (1977)

FIRST CESR PUBLICATIONS April 1980

CESR CLEO Upgrade National Science Board Approval –November 1984, $37.38 million –“Jewel of the NSF” CESR –Higher luminosity CLEO –Extensively rebuilt Project Execution –Outstanding Management

Superconducting RF R&D began in about 1980 –Proposal to build a small radius e+e- collider at the Z0 –Jefferson Lab (CEBAF) cavities –Longer Term Program High Q, Inexpensive Accelerating Structures Applications –Improved CESR Luminosity –B-Factory in CESR Tunnel –TeV e+e- Linear Collider –Synchrotron Light Source Energy Recovery Linac

Epilog CESR dominated b-physics –Until BarBar and Belle Continued innovation will guaranty future success Best wishes for the future
