First, a brief summary of the previous two parts…
On the Swiss-French border, near Geneva, there’s a place called CERN. Within its various buildings, modern-day alchemists scientists conCERN themselves with the fundamental structure of the universe. They disperse protons and other particles at near light speed and have them smash against one another, which creates various kinds of quark-gluon plasma and other mysterious physical phenomena. Then they apply titanic brainpower (math, physics, nuclear physics, quantum mechanics… all that), engineering capacity, and computing power to track the results of collisions of these fundamental particles.
We were there the other week and given a good long guided tour. Took lots of pics too…
The first accelerator we saw is called LEIR (the Low Energy Ion Ring). In it, lead ions are pooled. First the ions come from the LINAC-3 linear accelerator to LEIR, then they pass through to a PS ring, and then into a complex of big hoops, including the Large Hadron Collider (LHC).
