Giant magnets in the particle accelerator at Fermilab! The blue one is a dipole magnet used to bend the beam to make it curve around the ring. The red one is a quad-pole magnet used to focus the beam. The particles will spin millions of times around the 4-mile ring in the 10 seconds it takes to accelerate the particles.

This 3-foot tall bundle of copper-coated titanium wire will be stretched out to 100,000 feet to become the superconducting wire used in the accelerator.

The view from the 15th floor of Wilson Hall. On the right is the small booster ring which then feeds particles into the large ring which is only partially visible on the left.
