Question
The diagram shows a type of particle accelerator called a cyclotron.
Cyclotrons accelerate charged particles, following the path as shown.
An electric field acts on a charged particle as it moves through the gap between the dees. A strong magnetic field is also in place.
Once a charged particle has the required velocity, it exits the accelerator towards a target.
Which of the following is true about a charged particle in a cyclotron?
A. It increases speed while inside the dees.
B. It only accelerates while between the dees.
C. It undergoes acceleration inside and between the dees.
D. It slows down inside the dees and speeds up between the dees.
