Question

A new particle accelerator facility is being built. The designers are considering two designs, one using stationary targets and the other using collisions of beams with the same energy.

a. Consider a beam of protons with energy 213.0 GeV . If these protons collide with stationary protons, what is the available energy Ea in a collision? Express your answer in billions of electron volts to three significant figures.

b. Now, consider two beams of protons, moving in opposite directions, each with energy 107 GeV . What is the available energy Ea when these beams collide? Express your answer in billions of electron volts to three significant figures.
