Abstract

Micropole undulators for use in the generation of x-rays from moving charged particles are disclosed. Two rows of spaced apart poles are arranged so that each pole produces a magnetic field aligned with all other similar fields. The poles are the ends of C''-shaped magnets. In each row, adjacent poles are separated by spacers made of a superconducting material. 11 figs.

Micropole undulator

Patent Csonka, P L; Tatchyn, R O

Micropole undulators for use in the generation of x-rays from moving charged particles and methods for manufacturing such undulators are disclosed. One type of micropole undulator has two jaws containing rows of spaced apart poles arranged so that each pole produces a magnetic field aligned with all other similar fields. An external biasing field extends through the jaws so that an overall undulator field of substantially sinusoidal shape and substantially zero average value extends along the undulator axis. Preferably, the poles are bars formed of a magnetizable, but unmagnetized, material so that, after the jaws are assembled, all of themore » « less

Perspectives on micropole undulators in synchrotron radiation technology

Journal Article Tatchyn, R; Csonka, P; Toor, A - Rev. Sci. Instrum.; (United States)

Micropole undulators promise to advance synchrotron radiation (SR) technology in two distinct ways. The first is in the development of economical, low-energy storage rings, or linacs, as soft x-ray sources, and the second is in the opening up of gamma-ray spectral ranges on high-energy storage rings. In this paper the promise and current status of micropole undulator (MPU) technology are discussed, and a review of some practical obstacles to the implementation of MPU's on present-day storage rings is given. Some successful results of recent performance measurements of micropole undulators on the Lawrence Livermore National Laboratory linac are briefly summarized.

Micropole undulators: Novel insertion devices for synchrotron sources

Journal Article Toor, A; Csonka, P; Tatchyn, R - Rev. Sci. Instrum.; (United States)

Micropole undulators (wigglers) are undulators (wigglers) with submillimeter periods and are referred to, generically, as micropole insertion devices. Compared to ordinary insertion devices, whose period /lambda//sub /ital u// is typically /ge/l cm, micropole devices have periods smaller by a factor /ital f//le/10. Therefore, the first-harmonic radiation emitted by a micropole undulator will have its photon energy /ital E//sub /gamma// increased by /ital f/ and its spectral purity /Delta//lambda///lambda/ by /ital f/, provided the total length of the undulator /ital l//sub /ital u// stays unchanged, and magnetic field errors, as well as the electron-beam emittance, are sufficiently small. Furthermore, to generatemore » « less
