OVERVIEW OF THE EQUIPMENT IN FERMILAB'S CENTRAL HELIUM LIQUEFIED, TEVATRON'S COOLING SYSTEM.

SIX BUILDINGS WITH 24 COMPRESSORS AND 24 REFRIGERATORS ARE LOCATED ALONG THE TEVATRON, THE WORLD'S MOST POWERFUL ACCELERATOR. WITH HELP FROM THE CENTRAL HELIUM LIQUEFIER, THE REFRIGERATORS PRODUCE THE LIQUID HELIUM TO COOL THE SUPERCONDUCTING MAGNETS INSIDE THE TEVATRON TUNNEL. CAREFULLY ALIGNED, THE MAGNETS ARE NEEDED TO GUIDE PROTON AND ANTIPROTON BEAMS AROUND THE FOUR MILE LONG RING.
