the 20th Anniversary of the First Tevatron

Collisionshttp://www-cdf.fnal.gov/news/First-Tevatron-Collisions/

From 1985 to 2005Energy from 1.6 TeV to 1.96 TeV

Peak Luminosity from ~1024 cm-2s-1 to ~1.7 x 1032 cm-2s-1

Integrated Luminosity from ~0.1 mb-1 / year to ~1 fb-1 / year

Message from Leon to the CDF collaboration:

So if we define the TEVATRON as p bar p collisions, you are celebrating a great moment in Fermilab history. Wilson's vision of a superconducting machine that would reach towards one TeV and save electrical energy had been realized on July 2, 1983. Now we were after the highest collision energy, even though the colliding protons were filled with quarks, gluons, eggshells, and coffee grounds. And that success began on

October 13, 1985. I recall the usual "champagne in stryrofoam cups" celebration in the Control Room, Helen running around, Alvin smiling, John Peoples ...'and, and look at the

TEVATRON now! ' The highest energy, most luminous machine on the planet since then, and the next few years will bring fame even to outdo the White Sox!

1984 Dzero Collaboration Meeting

(Paul Grannis)

On behalf of DZero we would like to congratulate CDF and Fermilab on the twentieth anniversary of Tevatron Collisions. The Tevatron physics program has been enormously productive and successful, and we all owe a great deal of thanks to CDF for their pioneering efforts. We look forward to working with you as, together, we extend the physics reach of the Tevatron.

Yours

Jerry Blazey and Terry Wyatt

In 1985, theorists Eichten, Hinchliffe, Lane and Quigg were hanging around Aspen, attempting to impress girls by

reading them excerpts from the EHLQ report.

In 1985, theorist Joe Lykken was working at Los Alamos, on the ultra-top-secret project known as "The String Bomb".

He was already thinking of all the fun that we would be having for the next 20 years!

Someone out there right now is grinning just as broadly in anticipation of our next 20 years of fun and success at LHC and ILC.
