Fermilab - The 15-foot Bubble Chamber
A little-known relic of the early days of high energy particle physics, this massive stainless steel structure sits resplendent on the prairie at Batavia, Illinois.
On June 8, 2004, the bubble chamber was moved from its experimental home inside a nearby building to this public viewing area. Video

15-foot Bubble Chamber

The 15 foot diameter bubble chamber used at Fermilab during the 1970's was filled with a mixture of superheated liquid neon and hydrogen. A beam of high energy neutrinos was directed through the fluid, producing an electromagnetic shower of particle tracks consisting of microscopic bubbles.
