Artificial materials are structures that amplify electromagnetic waves by converting the kinetic energy of charged particle beams in particle accelerators, which are essential for particle research. Various types of accelerators, such as cyclotrons and linear accelerators, utilize electric and magnetic fields to accelerate particles. While these accelerators have applications in nuclear reactions and medical diagnoses, they cannot accelerate uncharged particles like neutrons or very light particles like electrons.

- 2. What is artificial materials ? Artificial materials are the structure that created and amplified electromagnetic waves by converting the kinetic energy of a charged particle beam into electromagnetic energy, and accelerate charged particle beams. 2
- 3. What is Particle Accelerator? A Particle accelerator is a device used for increasing the kinetic energy of electrically charged particles. The accelerators are the important instruments in conducting research concerning particles such as mesons, anti-proton, and anti-neutron. 3

- 5. Basic Principle In Electric Field a charged particle is accelerated. In Magnetic field a charged particle can be turned around. In magnetic field the magnetic force acts as a centripetal force. 5
- 6. Description & Design The accelerator consists of two flat semicircular metallic boxes named D1 and D2. The two Dees are separated by a narrow gap. The Dees are connected to the terminals of a high frequency oscillator. 6

- 8. Working Principle Its follows Fleming’s left hand rule. 8
- 9. Working Principle The positive ions emitted from the source will be accelerated in the gap towards the Dee which is negative at that time. If the ions emerge from D2 , the polarity of the applied potential is reversed, the positive ions will again face the negative Dee and thus will be again accelerated by the Electric in the gap. 9
- 10. Calculation Radius The magnetic force acting on the charge particle is given by As this force acts as centripetal force, so we have 10
- 11. Angular velocity Above equation represents the angular velocity Frequency Above equation represents the frequency of circulating charge 11
- 12. Time Period This is the required time period of circulating charge. Kinetic Energy This is the required kinetic energy of the circulating ion. 12
- 13. Application or Uses • Accelerator is used to bombard nuclei with energetic particles and observe the nuclear reactions. • Artificial Material is used for different radioactive tests in hospitals for diagnosis. Like in the treatment of Cancer. 13
- 14. Limitations • It cannot accelerate neutron, because neutron do not have any charge. • It cannot accelerate electron because of its small mass. 14
