Description of Facility/Instrument : This was a 6.2 GeV protron syn- 

 chrotron with various secondary beams. After completion of its 

 operation as a high-energy physics facility, the Bevatron was 

 placed into service for research in nuclear physics and remains 

 in use as part of the Bevalac.
