FERMILAB PROTON SYCHROTRON 



Fermi National Accelerator Laboratory (Fermilab) 



U.S. Dept. of Energy 



"Big Science" Descriptor : High-energy physics 



Description of Facility/Instrument : This conventional magnet synchro- 

 tron of 6000-foot diameter provided protons at 400 billion elec- 

 tron volts (GeV), which was twice the design energy, and various 

 secondary beams from fixed targets. It is now used at 150 GeV as 

 an injector into the new superconducting sjmchrotron which up- 

 graded the facility under the Energy Saver project, described 

 separately. Other upgrades include Tevatron I and Tevatron II, 

 also described separately, which integrate extensive new capabili- 

 ties Into the Fermilab accelerator complex. 



Date of Construction : 1968-1974 



Construction Cost : Original : $248 million 



1984 $$ : $727 million 



Present International Cooperation 



Nationality(s) of Ownership : U.S. 



Nationallty(s) of Operational Funding : U.S. 



Nationallty(s) of Management Staff : U.S. 



Nationality(s) of Researchers : Largely U.S., but includes 



Argentina, Belgium, Brazil, Canada, China, England, France, 

 Greece, India, Israel, Italy, Japan, Mexico, Poland, South 

 Korea, Spain, Sweden, Switzerland, the U.S.S.R., the Federal 

 Republic of Germany, and Yugoslavia 



Because high-energy physics is an international activity, 

 with knowledge freely shared among its practitioners, this 

 laboratory has extensive interactions with people and 

 Institutions in foreign countries. 



Of 348 experiments approved to run at Fermilab, 148 have 

 had scientists taking part from institutions outside the 

 United States. Typically, about 600 physicists are involved 

 in the Fermilab research program each year, of which over 

 one-fourth are from foreign institutions. Generally, scien- 

 tists from about 20 countries are Involved in the program 

 at any one time. 



There are three government-to-government agreements in- 

 volving high-energy physics which affect Fermilab. These 

 are with the U.S.S.R., the Peoples Republic of China, and 

 Japan. 



Potential for Future International Cooperation ; As at all forefront 

 world hlghenergy physics facilities, beam time is available 

 without charge for the best research proposals worldwide. Foreign 

 researchers have provided substantial pieces of capital equipment 

 for experiments. Such collaboration would be expected to continue.
