D-ZERO DETECTOR AT FERMILAB 



Fermi National Accelerator Laboratory (Fermllab) 



U.S. Dept. of Energy 



"Big Science" Descriptor : High-energy physics 



Description of Facility/Instrument ; This facility provides detection 

 capabilities complementary to those of the collider detector 

 (CDF), effectively doubling Tevatron I physics utilization by 

 operating simultaneously. It is optimized for accurate measure- 

 ments of energies of electrons, muons, and jets of hadrons. It 

 has no magnetic field; energies are measured with calorimeters 

 only. High resolution calorimetry will allow excellent identifi- 

 cation of missing energy in an Interaction. The D-Zero Detector 

 has very complete large solid angle coverage. 



Date of Construction : 1985-1989 (See note below.) 



Construction Cost ; 1984 $$ : $43 million (est.) (See note below.) 



Present International Cooperation 



Natlonality(8) of Ownership ; U.S. 



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



Nationallty(s) of Management Staffl U.S. 



Nationality(s) of Researchers ; (See the Fermllab Proton Synchro- 

 tron for a list of international researchers and a discussion 

 of International cooperation.) 



Potential for Future International Cooperation ; See the discussion 

 under the Fermllab Proton Synchrotron. 



Other information : 



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.
