A View from NSFThe Early Years of CESR

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)– 1993 -2000
• My first recollection of CESR– Late 1974 or early 1975
• After the J/ Ψ discovery
• ~Two-Year process of approval
J ParticlePRL 33 1402 (1974)
Ψ ParticlePRL 33 1402 (1974)
Four known vector mesons ρ, ω,Φ,J/Ψ.Were there others?
CESR ProposalIEEE Transactions on Nuclear Science, Vol. NS-24, No.3, June 1977
CESR - AN ELECTRON POSITRONCOLLIDING BEAM FACILITY AT CORNELL
M. TignerCornell UniversityIthaca, N.Y. 14853
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 SLAC2. Construct ISABELLE at
Brookhaven3. Support R&D for 1 TeV Fixed
Target & Collider at Fermilab4. 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 39 252 (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
