“…These approaches have often been encumbered by either an increase in the total power delivered by the undulator or the limited tunability of the radiation energy. These restrictions have limited the use of small-period undulators to specialized applications at storage-ring-based light sources and free-electron lasers (FELs) [Wulff, 2002 (beamline ID-09 at ESRF employs an in-vacuum undulator with 1.6 cm period and 6 mm gap speci®cally designed for time-resolved research using 15 keV X-rays); Ho et al, 1991;Varfolomeev et al, 1992].…”

A concept for variable-period undulators for the production of synchrotron radiation from both medium- and high-energy storage rings is described. This concept is based on a staggered array of permeable poles placed in a magnetic solenoid that produces a longitudinal field. The concept permits variations in the short magnetic period of the undulator of as much as 100%. The unique capabilities of such undulators will allow them to be tuned by the variation of the period length and of the solenoid field. The device can be operated at either constant flux or constant power, independent of X-ray energy. It is expected that the new concept will have a major impact on the production and applications of X-rays because of the inherent simplicity and flexibility of the design and the absence of radiation damage. Analyses of the magnetic and mechanical design concepts are presented.

“…Scheme [4] gives a small increase of the magnetic field in comparison with the configurations of [2,3]. In an attempt to mitigate the segmentation problem further without sacrificing field strength some novel schemes utilizing steel monoblocks and bias PMs were recently investigated by us [5,6]. Scheme [6] in particular provides a comparatively high magnetic field amplitude.…”

Selected novel hybrid/permanent magnet (hybrid/PM) configurations as elements of high-field helical undulators are considered. The general approach is found to be capable of attaining on-axis magnetic field amplitudes exceeding 0.4 T for a 0.5:1.0 gap:period ratio and at least two of the configurations can be constructed exclusively out of steel and permanent magnet monoblocks. Such simplified magnetic structures can improve the effectiveness and economy of small-scale, short-period undulator designs.
