Abstract = {{The growing demand for spectroscopic studies requiring high linear or
   circular polarization rates has stimulated the design of exotic sources
   and specialized beamlines.  At the ESRF, it has been proposed to build a
   new type of helical undulator (HELIOS).  The first prototype will be
   installed on beamline No. 6 which is a high priority international
   beamline dedicated to X-ray spectroscopy or dichroism at low excitation
   energy (0.5-10 keV).  HELIOS will be segmented into two identical
   modules with slightly deflected injection axes:  the output will thus
   consist of two well separated beams with fully independent control of
   polarization.  Two types of optics should be available:  (i) low energy
   experiments will be carried out on a side branch equipped with grating
   optics:  (ii) Bragg optics will be developed on the straight branch and
   used for experiments at higher energies.  This paper deals with
   preliminary design considerations related to the high energy branch
   only.  Special attention was paid to minimize the energy difference
   between the two separated excitation channels and to preserve the
   excellent polarization characteristics of the source.  This led us to
   propose the construction of a four-mirror collimation device making the
   two incident beams rigorously parallel.  In principle, the highest
   circular polarization rates should be obtained with a modular
   `'twisted'' {[}2 + 2]-crystal monochromator, but at the expense of a
   significant loss of intensity.}},
