• 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

Four known vector mesons ρ, ω,Φ,J/Ψ.Were there others?

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

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
