COLLIDER DETECTOR AT FERMILAB (CDF) 



Fermi National Accelerator Laboratory (Fermilab) 



U.S. Dept. of Energy 



" Big Science" Descriptor ; High-energy physics 



Description of Facility/Instrument ; This versatile research detector 

 is capable of recording the results of antiproton-proton colli- 

 sions at reaction energies up to 2000 GeV; detecting hundreds of 

 simultaneously created particles; and identifying photons, elec- 

 trons, muons, and hadrons separately. It measures energies of 

 charged particles with a strong magnetic field and of all parti- 

 cles (except neutrions) with massive calorimeters. 



Date of Construction ; 1981-1986 (See note below.) 



Construction Cost ; 1984 $$ : $54 million (See note below.) 



Present International Cooperation 



Nationality(s) of Ownership ; - U.S. 

 Nationality(s) of Operational Funding ; U.S. 

 Nationality(s) of Management Staff ; U.S. 



Nationallty(s) of Researchers ; (See the Fermilab Proton Synchro- 

 tron for a list of international researchers.) 



Funding over six years includes about $39 million (In 1984 

 dollars) from the Dept. of Energy, plus $15 million from Japanese, 

 Italian, and National Science Foundation-supported collaborators. 



Potential for Future International Cooperation ; See the discussion 

 under the Fermilab Proton Synchrotron. 



Other Information ; This facility is expected to be ready for test run- 

 ning in 1985 and for its first physics research use In October 

 1986. 



Note; This detector was not built as a construction project. It 

 was fabricated using capital equipment funds. Therefore, "Date 

 of Construction" and "Construction Cost" in this case refer to 

 this type of fabrication.
