TEVATRON II - 1000 GeV FIXED TARGET RESEARCH FACILITIES 

 Fermi National Accelerator Laboratory (Fermllab) 

 U.S. Dept. of Energy 



"Big Science" Descriptor : High-energy physics 



Description of Facility/Instrument ; The Tevatron II provides the 

 necessary facilities for a 1000 GeV fixed target experimental 

 program in existing areas to fully exploit the higher energy of 

 the superconducting accelerator complex, now referred to as the 

 Tevatron. Tevatron II provides a unique opportunity for producing 

 secondary particle beams at higher energies and intensities than 

 anywhere else in the world. There are four new secondary beams 

 and eight other upgraded beams. These 12 can be run simul- 

 taneously. The eight upgraded beams are completed and operating.
