OUTCOME
By the end of this lesson I will be able to describe the progress of early synchrotrons and describe the properties of synchrotron radiation
Electric fields and electric charge enable us to accelerated charged particles, but what are they?
LEARNING TASKS
Explain
Explore and Elaborate
Cyclotrons and other accelerators use electric fields to move charged particles. In the activity below you will make your worn ball cyclotron.
Evaluate
Answer all the questions from Explain and the practical activity
1. Use a diagram how you can pick up paper with a statically charged balloon
2. How is electric charge generated in neutral materials?
3. What is the fundamental charge? What is its size?
4. What does it mean that electric charge is quantised? How many electrons make up 1 Coulomb of charge?
5. What is stronger, gravity of charge? What evidence supports this?
6. Draw the field lines around an electron and positron
