A synchrotron uses a cyclic particle accelerator to accelerate charged particles to very high energies using alternating electric and magnetic fields. The first electron synchrotron was constructed in 1945 by Edwin McMillan at the University of California, designed for energies between 320-350 MeV. A synchrotron consists of an electron gun, linear accelerator, booster ring, storage ring, beamline, and end station to produce and direct beams of synchrotron light for applications in spectroscopy, crystallography, medical imaging, and cancer therapy.
The electron synchrotron
- 3. A synchrotron is a cyclic particle accelerator in which a charged particle is accelerated to very high energies in the presence of an alternating electric field while confined to a constant circular orbit by a magnetic field.
- 4. THE Electron Synchrotron was first constructed by EDWIN MCMILLAN at the University Of California in1945. It was designed for 320 –to-350 Mev Energy Range.
- 6. Electron Gun Linear accelerator or LINAC Booster ring Storage ring Beam line End station
- 8. The Electron Gun : A heated cathode produces free electrons which are pulled through a hole in the end of the gun by a radio frequency electric field.
- 9. Linear accelerator is used for the preliminary acceleration of electrons upto energies of 50 to 100 kev.
- 10. The linear accelerator feeds into the Booster Ring which uses magnetic field to force the electrons to travel in a circle.
- 12. The Booster Ring feeds electrons into the Storage Ring, a many sided doughnut shaped tube. The doughnut shaped vacuum chamber is enclosed in a ring of C-shaped magnet.
- 15. After the beam of light is generated in the storage ring it travels towards the experimental station.
- 16. After travelling through the beam line, the radiation can finally be used in the various experiments.
- 17. Based on : Directing beams to hit specific targets or colliding beams onto each other. Production of thin beams of synchrotron light.
- 18. Synchrotron radiation covers spectroscopy, X-ray microscopy, crystallography of proteins. In medicine,beams are used for Positron Emission Tomography(PET), therapy of tumours,and for surgery.
