The planned XFEL at the Paul Scherrer Institut, the SwissFEL, is a fourth generation light source. Meanwhile the first
hard X - ray FEL was taken into operation, the LCLS at Stanford, USA. Two further hard XFELs are in construction.
One in Hamburg, Germany and the second at Spring - 8, Japan. Thanks to the beam properties of the XFEL, these new
sources promise to bring novel insights and breakthroughs in many scientific disciplines. For engineers and designers
new challenges arise in terms of material choice, damage thresholds and beam property conservation. The Swiss Light
Source optics group is currently working on the beamline optics design of the SwissFEL beamlines. The preliminary
optics design of the two undulator beamlines which serve six experiments is under preparation. In this article a
preliminary layout of the hard X - ray Aramis undulator beamline is presented. Several beamline designs have been
evaluated. Beam deflection and splitting via mirrors and diamonds is presented. The SwissFEL is planned to be
operational in 2016.
