Cyclotron Radiation

(radiation emitted when charged particles are accelerated)

Cyclotron Radiation is radiation emitted by a charged particle when it is accelerated and traveling at less than Relativistic Speed. It can be generated in Magnetic Fields in space. Characteristics:

  • A spike in the spectrum at the Frequency of the particle's orbit, i.e., the Cyclotron Frequency.
  • Harmonics at integral factors.
  • Polarization characteristics dependent upon the directions of observation and of the magnetic field.

The period of the particle's orbit is inversely proportional to the magnetic field, making such radiation a means detecting characteristics of magnetic fields.

Radiation from near-light-speed charged particles is called Synchrotron Radiation.
