An aerial view of the center of Lawrence Berkeley National Laboratory, located on a hill behind the University of California campus. In the center can be seen the circular building of the old 184-inch cyclotron -- now housing an accelerator called the Advanced Light Source.

 Canada's Tri-University Meson Facility, TRIUMF, the world's largest cyclotron. The diameter of the machine is about 18m and ions travel a total of 45km and, as they spiral outward, are accelerated to 520MeV. The machine started in 1974 and is still in operation.

 The inside of a Radio Frequency Quadrupole. The RFQ has generally replaced the very large Cockcroft-Waltons as the first stage of injectiors into synchrotrons.

 An overview of the European high energy physics laboratory CERN. Superimposed on the photo is an outline of the ring (deep underground) of LEP, this tunnel later to be used for the Large Hadron Collider.

 The Relativistic Heavy Ion Collider, RHIC, at Brookhaven National Laboratory has been used to study nuclear matter under extreme conditions of very high density and very high temperature similar to the conditions in the original Big Bang. Here we see the result of a collision of a nucleus of gold with a nucleus of gold. The temperature, in a collision, rises to 2 trillion degrees Kelvin and as many as 10,000 particles are born in the resulting fireball.

 Photography as 16 GeV negative pions traverse the first CERN liquid hydrogen bubble chamber; it was only 30 cm in diameter.
