1. How can you determine whether particles are mesons or baryons by looking at their quark structure?
2. Does it appear that the total baryon number of the universe is zero? What would that mean?
3. Explain how a magnet may be used to distinguish a range of energies for protons. How can a monoener- getic beam of protons be obtained?
4. Why is it a problem when a particle gets out of phase with the frequency of a pulsed accelerator?
5. Explain why electron accelerators that are not linear must have large radii. The largest such accelerator is the LHC at CERN, which has a radius of 4.3 km.
6. The next proposed accelerator is an electron-positron collider that may be many kilometers long. Why must it be so long? Why can't it be circular to save space?
