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.

Looking through a copper tube at Fermi National Laboratory. These tubes are used to accelerate particles to precise and fast speeds while taking up minimal space. Particle accelerators can be used to do very precise radiation therapy for some forms of invasive and difficult to treat cancer rumors! #accelerator #fermi #research #science #particles #radiationtherapy
Cryogenic Dark Matter Search at FermiLab Accelerator Laboratory in Illinois.
Dark matter makes up more than one fifth of the universe, and no one knows what it is made of. Located half a mile underground in a mine in North Minnesota, the CDMS experiment uses hexagon-shaped detectors made of germanium and silicon to look for dark matter particles.
This is a model that visualizes the recorded data and makes it audible! If you stand by this machine you can hear the sounds of particle events. The white panels light up with each sound as it happens.

Copper cavity at Fermi National Accelerator Laboratory.
To accelerate particles to high energies, particle physicists use electromagnetic waves oscillating at radio frequency.
This set of copper cavities is shaped to host a wave of 805 megahertz, about the frequency at which a cell phone operates.
A beam of particles enters the line of cavities through a hole on the side and “rides” the wave, gaining speed and energy.
The Fermilab Linear Accelerator has a line of 30 Copper cavities that accelerate protons to 0.75 times the speed of light.
