Introduction
We can use the crossed fields to accelerate the charge particles.
Pre-Requisites:
Knowledge about the motion of charge in electric and magnetic field.
Activity:
Study about cyclotron and observe what effect will frequency of cyclotron has on its energy.
Real Life Question:
Why an ion moves in a circular path in crossed E and B?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Cyclotron frequency | Frequency at which cyclotron operates. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Cyclotron | It increases the speed of any charge particle in presence of electric and magnetic field. |
Real life uses :
To produce high energy beam, To treat cancer and radiations.
Places to visit :
Nuclear physics labs, Radiation treatment labs.
Practical examples around us
| Examples | Explainations |
|---|---|
| Nuclear physics | This phenomenon is used to produce the high energy beams in the nuclear physics. |
What you learn in Theory:
The operation of the cyclotron is based on the fact that the time for one revolution of an ion is independent of its speed or radius of its orbit and this is used to accelerate the ions.
What you learn in Practice:
Cyclotron is a device used to produce high energy beams and to treat cancer tumors. It works on the fact that in every circle of ion its energy increases.
