Electric fields

Question 1

Explain what is meant by ionisation.

Answer 1

Ionisation is when an atom / molecule loses (or gains) one (or more) electrons ✔

Question 2

Discuss the energy transfers that take place in the accelerator as the ion passes through it. Assume the ions are in a perfect vacuum.

Answer 2

Potential energy of ion is transferred to kinetic energy of ion✔
Power supply transfers energy to the ion✔
Decrease in energy stored in supply = increase in (kinetic) energy stored by the ion✔
