[Editor’s Note: Nuclear Science Week was pointed out to us on the tips line by Elizabeth Eckhart, along with a commitment to contribute. If you’d like to see AtomicToasters come back from its Chernobyl-like radioactive slumber, you should follow Elizabeth’s lead, and send in
stuff for the rest of us to discuss. You can also follow Elizabeth’s Twitter account at @elizeckhart] Continue reading Why The World Needs Nuclear Power
There’s a scene in The Hunt For Red October where Jack Ryan is trying to figure out how to get Captain Ramius and anyone involved in his defection plan off the Red October without the crew getting suspicious. He’s racking his brain trying to figure it out. Then it hits him. We’ve all been there. A problem is rattling around in our brain and we just can’t seem to find a solution. It could be finding a way to solve a problem in an engineering design, or finding the inspiration to write, or figuring out how to fix something. We can spend hours, days, or weeks trying to come up with a solution.

Good morning everyone.
Today we’re going to talk about particle accelerators, fascinating machines that have greatly expanded our knowledge of what matter is, and also of how the universe came into being. There are a great number of particle accelerators in use today, the newest and largest of which is the Large Hadron Collider that is located on the border of Switzerland and France, and operated by CERN. The LHC is the latest iteration in a long series of machines made to study the atomic structure of matter, with the first machines being made in the 1920s.
All particle accelerators use electric fields for the acceleration of charged particles to high energies and the confining of those particles into a defined and controlled beam. The beam is directed at various types of targets and materials and the interaction of the beam and the target matter is studied, typically by examining the tiny pieces of the atoms in the target that go flying off in all directions. Particle accelerators were called atom smashers for a long time for this reason. The manner in which the electric fields are applied varies widely, but particle accelerators fall into two basic categories, electrostatic accelerators and oscillating field accelerators, also known as radio frequency (RF) accelerators.
