Description:

WORKER IN THE PEP STORAGE RING TUNNEL. THE PEP STORAGE RING IS ONE OF TWO OPERATIONAL ELECTRON POSITRON STORAGE RINGS LOCATED AT THE SLAC. BEAMS OF ELECTRONS AND POSITRONS CIRCULATE WITHIN THE RING IN OPPOSITE DIRECTIONS AND COLLIDE AT SEVERAL POINTS, CREATING VARIOUS SUBATOMIC PARTICLES IN THE PROCESS. RESEARCHERS STUDY THE BEHAVIOR OF THESE NEW PARTICLES, GAINING INSIGHT INTO THE NATURE AND STRUCTURE OF THE SUBATOMIC WORLD AND THE FORCES THAT OPERATE THEREIN. THE ELECTRON AND POSITRON BEAMS OF THE PEP STORAGE RING CIRCULATE IN A VACUUM PIPE INSIDE A SERIES OF MAGNETS. THE LONG RECTANGULAR BLOCKS ARE BENDING MAGNETS, WHICH DEFLECT THE BEAM INTO A CIRCULAR PATH. THE SMALLER BLOCKS ARE FOCUSING MAGNETS, WHICH KEEP THE BILLIONS OF PARTICLES IN THE BEAM BUNCHES TIGHTLY TOGETHER. PEP IS APPROXIMATELY ONE AND ONE HALF MILES IN CIRCUMFERENCE AND CAN ACCOMMODATE PARTICLE BEAMS OF UP TO 18 BILLION ELECTRON VOLTS (GEV).
