Introduction Synchrotron radiation is the electromagnetic radiation
emitted when charge particles travel in curved path.
In Synchrotron the charge particle moves with
constant relativistic speed on a circular arc.
The relativistic speed domain make it different from
Cyclotron.

Introduction (Cont.…) A synchrotron produces light by using radio frequency
waves and powerful electro-magnets to accelerate
electrons to nearly the speed of light.
Energy is added to the electrons as they accelerate so
that, when the magnets alter their course, they
naturally emit a very brilliant, highly focused light.

Historical Background Synchrotron radiation was named after its discovery in a General Electric
synchrotron accelerator built in 1946 and announced in May 1947 by
Frank Elder.

Properties of
Synchrotron
Radiation
• High Intensity
• Continuous Spectrum
• Excellent Collimation (Brilliance)
• Low Emittance
• Pulsed-Time Structured
• Polarization

Advantages of
Synchrotron
Radiation
• An Example. The intensity of synchrotron X-rays is
more than a million times higher that of X-rays from
a conventional X-ray tube. Experiments that took a
month to complete can now be done in only a few
minutes.
• With synchrotron radiation, molecular structures
that once baffled researchers can now be analyzed
precisely, and this progress has opened up many
new research fields over the last few years.
