- be able to describe how the particles can be steered
- be able to describe the particle trajectory in a cyclotron
- be able to explain what synchrotron radiation is and how it can be generated
- be able to write down the equations of motion for a charged particle in an electromagnetic field
- be able to write down the formulas for the calculation of the fields generated by a arbitrarily moving charged particle
- be able to describe the properties of a superconductor
- be able to describe a storage ring
- be able to describe a linear accelerator

*Skills and abilities*

For a passing grade the student must

- be able to calculate the particle trajectories for a number of important special cases
- be able to use the Lorentz transformation
- be able to calculate how fields and sources transform with a change of reference frame
- be able to apply the method of images
- be able to solve electromagnetic problems using a commercial finite element program
