What is a synchrotron...Article...???

What is a synchrotron?
A synchrotron is a machine that accelerates charged particles such as electrons to extremely high energies...creating an electron beam that travels at almost the
speed of light...Itz done by creating strong magnetic a
nd electric fields and
simultaneously increasing the strength of the fields..Powerful electromagnets are used to focus and steer the beam inside a ring-shaped vacuum chamber...which minimises collisions with air molecules and allows storage of the beam at high energy levels for many hours...

How does the Australian Synchrotron work?
1. Electrons are produced at the electron gun by thermionic emission from a heated tungsten matrix cathode.
2. The linear accelerator accelerates the electron beam to an energy
of 100 MeV (mega electron volts) over a distance of about 10 metres.
3. The booster is an electron synchrotron 130 metres in circumference that takes the 100 MeV beam from the linac and increases its energy to 3 GeV (giga electron volts).
4. The storage ring is the final destination for the accelerated electrons. It can hold 200 mA of stored current with a beam lifetime of over 20 hours.
5. Individual beamlines are positioned to capture the synchrotron light given off by the storage ring.
6. Experiments employing synchrotron light are conducted in customised facilities
called end-stations...
