Physicist Tom DiMarco shows visitors a scale model of the Fermi Accelerator Laboratory at Fermilab. The large ring is the Tevatron Collider, one of the largest particle accelerators in the world. It has a circumference of 4 miles!
Fermilab collaborates with more than 20 countries on physics experiments based in the United States and elsewhere.
This is a Full Scale Model of a Tevatron Collider: FermiLab’s most powerful accelerator.
Particle physics research is all about getting a very precise beam of particles to accelerate to a very high speed. Magnets keep the particle beam on track as it circles the particle tube. Particles go around the accelerator loop until they reach adequate speed, then are slammed into a six story high particle detector. This causes the particles to break apart and create trails in the detector. Physicists study the particle trails to understand more about our universe.
This Tevatron is special because it accelerates particles to 99.9999954% the speed of light. A particle will circle 4 miles of particle accelerator 1 million times before crashing into the particle detector.
The particle beam must be very accurate and focused to ensure particles can get to proper speeds for study. Particle speed and accuracy is managed by magnets. The blue sections of the accelerator are Dipole magnets used to steer the particle beam as it goes through the accelerator. The red sections are made up Quadrupole magnets used to focus then beam, ensuring it is small and keeping it from spreading. Finally, the yellow sections contain Hexapole magnets used for small corrections in the particle beam.
