Which of the following devices is used to accelerate charged particles to high velocities?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. cyclotron.
Among the devices listed—cyclotron, cosmotron, copatron, and cryotron—the cyclotron is specifically designed to accelerate charged particles to high velocities. Invented by Ernest Lawrence, a cyclotron propels charged particles outward from the center along a spiral path using a static magnetic field and a rapidly varying electric field.
- The cosmotron was also a particle accelerator but was not as widely used as the cyclotron.
- The cryotron is a cryogenic electronic device unrelated to particle acceleration.
- The term copatron does not correspond to any known particle accelerator.
