Encyclopedia > Radiation damping

Radiation damping in accelerator physics is a way of reducing the beam emittance of a beam of accelerated charged particles. The effect of synchrotron radiation is to reduce the dispersion of the beam and thus the emittance. Accelerator physics deals with the problems of building and operating particle accelerators. ... The beam emittance of a particle accelerator is the amount of spread of the beam as it travels. ... Hannes Alfvén, and Nicolai Herlofson, predicted synchrotron radiation in space in 1950 [1] Synchrotron radiation is electromagnetic radiation, similar to cyclotron radiation, but generated by the acceleration of ultrarelativistic (i. ...

Synchrotron radiation - Wikipedia, the free encyclopedia (971 words)
Synchrotron radiation is electromagnetic radiation, similar to cyclotron radiation, but generated by the acceleration of ultrarelativistic (i.e., moving near the speed of light) electrons through magnetic fields.
Current third generation synchrotron radiation sources typically are heavily based upon these insertion devices, when straight sections in the storage ring are used for inserting periodic magnetic structures (composed of many magnets that have a special repeating row of N and S poles) that force the electrons on a sinusoidal path or helical path.
Synchrotron radiation is used in particle accelerators in radiation damping, a method of reducing beam emittance.
Proceedings of the Oklahoma Academy of Science (2219 words)
The mechanical wave in the secondary spring is analogous to radiation, and is referred to as mechanical radiation.
Damping is clearly exhibited, and the frequencies are lowered by the damping.
The advantage of the present model is that it may allow better visualization of radiation damping, as well as visualization of the interaction between the oscillator and the "radiation field".
