The present status of system- and technical design and R&D for the new heavy ion synchrotrons SIS100 and SIS300 and the HEBT system is summarized. The overall machine planning and the general layout has been completed and the detailed technical machine design has been started. Device and component specifications, technical parameter lists and technical design reports are in preparation with the goal to enable international partners or industry to finalize the component design to achieve production readiness. In the frame of international working groups the distribution and sharing of the work packages, especially of the cryomagnetic system is under discussion.

The ion optical layout of the two synchrotrons SIS100/300 of the FAIR project is presented. SIS100 will provide high intensity ion beams of all species from H to U up to a magnetic rigidity of 100 Tm. To minimize the space charge effects and to reach the necessary ion intensities for the FAIR project SIS100 will be operated with intermediate charge state heavy ions (U28+). The ion optical layout of SIS100 has been optimized for this purpose. The layout assures the separation of beam particles which are ionized by collisions with residual gas molecules from the circulating beam. Since SIS100 and SIS300 will be installed in the same tunnel, the lattice layout of SIS300 has to follow precisely the geometry of SIS100. SIS300 will provide beams of highly charged heavy ions with a maximum rigidity of 300 Tm. In addition, it will function as a stretcher ring for SIS100. The beam transfer system from SIS100 to SIS300 is designed to fit in a single straight section of the two machines. The effect of dynamic field errors in SIS300 has been considered and the maximum tolerable error levels for the operation of SIS100, such as tracking errors and power supply ripples have been investigated.

The proton and heavy ion synchrotrons SIS100 and SIS300 are the heart of the new FAIR facility which is under construction on the site of the present GSI. All ions from protons to uranium will be accelerated up to a magnetic rigidity of 100 Tm and 300 Tm, respectively. The design of the beam extraction system of both synchrotrons is completed and will be presented in this paper. The extraction devices of both synchrotrons are situated in one common straight section and deflect the beam vertically. SIS100 has been optimized for fast extraction by means of a distributed fast bipolar kicker system. However, slow extraction over a few seconds is also foreseen. SIS300 has been optimized for slow extraction and may generate spills of up to 100s. The slow extraction channel combines horizontal deflection by an electrostatic septum in the first stage with vertical deflection by a Lambertson septum magnet and subsequent magnetic extraction septa in the second stage. An emergency beam dumping system could be integrated in the extraction system of both machines.
