wiggler

[′wig·lər]
(nucleonics)
A system of transverse, periodic electromagnetic fields, generally used in a storage ring or synchrotron to increase the intensity of synchrotron radiation, increase reaction rates in high-energy physics experiments, produce quasimonochromatic photon beams, and amplify photon beams from other sources, as in the free-electron laser.

If you took the left-hand path, you saw a compost heap filled with the living versions of the work's oversize mutation: actual Tennessee wigglers. At the end of these paths (which was also their starting point), the worm sculpture pierced several walls that divided the space of the show into compartments and organized the worm's open circular structure.
FEL operators can adjust the wavelength of the laser's emitted light by adjusting the distance between the magnets in the wiggler.
Chapter 3 focuses on incoherent undulator radiation, which is produced by extremely long period synchrotron undulations, while the free-electron laser relies on coherent emission processes and does not require long periodic magnetic wiggler fields.
An experimental I-Linac FEL, utilizing a 4 meV beam as input power and a tapered wiggler has repeatedly produced peak powers in excess of 1-gigawatt on a wavelength of 9-millimeters.
Felicia McKee of Johnson City, Tennessee, is capitalizing on these lowly red wigglers. As a Certified Naturally Grown producer, a grassroots alternative to Certified Organic, she needs plenty of compost for her gardens.

In the late '70s, as the SSRL ring was transitioning from parasitic to partially dedicated operation, SSRL scientists demonstrated that a special magnet called a multipole wiggler could simultaneously increase the flux of synchrotron radiation and push the spectrum to shorter wavelengths.
The team has since used the wiggler beam to examine samples as tiny as 0.042 micrometer across.
