The electron synchrotron
1.
2.
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
7.
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.
11.
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.
