Undulators in synchrotron radiation
WebSynchrotron radiation research is rapidly expanding with many new sources of radiation being created globally. Synchrotron radiation plays a leading role in pure science and in emerging technologies. The Journal of Synchrotron Radiation provides comprehensive coverage of the entire field of synchrotron radiation and free-electron laser research … WebUndulators and wigglers. When faster damping is required than can be provided by the turns inherent in a damping ring, it is common to add undulator or wiggler magnets to induce more synchrotron radiation. These are devices with periodic magnetic fields that cause the …

The electron transfer process has been widely investigated using … WebJun 24, 2024 · The FELs use the same undulators as those in storage ring-based light sources, but thanks to an electron clumping effect called “micro-bunching,” the resulting synchrotron radiation is orders of magnitude more coherent and intense.
WebAug 30, 2024 · The target operational beam emittance is lower to around 80 pm rad. HEPS is a high-performance and high-energy synchrotron radiation light source with a beam energy of 6 GeV and an ultralow emittance of better than 60 pm. HEPS mainly consists of 500 MeV linac, 454.5 m booster, storage ring, beamlines, and end-stations. WebAug 26, 2024 · SPECTRA is an application software to calculate optical properties of synchrotron radiation (SR) emitted from bending magnets, wigglers (conventional and elliptical) and undulators (conventional, helical, elliptical and figure-8). Calculations of radiation from an arbitrary magnetic field distribution are also available.

An undulator is an insertion device from high-energy physics and usually part of a larger installation, a synchrotron storage ring, or it may be a component of a free electron laser. It consists of a periodic structure of dipole magnets. These can be permanent magnets or superconducting magnets.

That is, undulator radiation characterized by the radiation being concentrated in discrete harmonics is produced when K < 1. For K > 1 the radiation spectrum is that of synchrotron radiation and is characteristic of wigglers. From Eq. jeff lee football recordWebOne final remark concerning the undulator equation is that the wavelength observed changes significantly with observation angle but since there is a θ 2 term the wavelength always lengthens as the observer moves away from the on-axis position (θ = 0).
