1.5 Electron Positron Collisions and Linear Colliders
summary
Collisions
• In the 1970s, particle accelerators were developed that could collide particles.
• Proton–proton collisions are complicated because there are many components in protons, so the initial conditions of the experiment are not known.
• Electron–positron collisions are simpler because all the energy goes into the final products.
Colliders
• Circular and linear accelerators each have advantages and disadvantages, which include cost differences and the need to account for synchrotron radiation (electromagnetic radiation emitted when a charged particle is accelerated radially).
