undulator

[′ən·jə‚lād·ər]
(nucleonics)
A wiggler that has a relatively low magnetic field, resulting in coherent emission of radiation from all wiggles simultaneously, and has a relatively low-energy, directed or collimated beam of radiation that is comparable to a laser in many characteristics. Also known as interference wiggler.

The calculated reduction would be at a ratio of 100:1, in other words, for every 100 revolutions of the propeller at the input of the gear, its output would be only one revolution, traveling only one cog on the final gear of the undulator (Fig.
A design of FEL based EUV light source can be made by the one-dimensional FEL theory (82) as follows: The FEL amplification takes place in the undulator with the undulator period [[lambda].
Since the construction of the ESRF there have been significant developments in the performance of insertion devices [28], with small-gap undulators and fine tuning of the magnets to allow very high brilliance x rays and high-energy operation with high-order harmonics.
The undulator won't fit in most biology laboratories, because it requires an electron storage ring to function, such as the half-mile-diameter ring used at Cornell.
An undulator has a mechanical drive system which allows for adjustment of the gap between the magnet girders with m-accuracy while magnetic forces of up to 3 tons are present.
To achieve this radiation with a 2 cm-period undulator, the energy of the electron beam must be around 5 GeV.
The photon energy of 585 eV was chosen for maximum contrast between the Ge and surrounding silicon nitride window, and to match the peak of the undulator second harmonic to yield a high photon flux.
