The FLAIR Facility

The scientific program proposed by the FLAIR and SPARC collaborations is based on the availability of low and ultra-low energy beams of antiprotons, highly charged heavy ions and exotic nuclei at FAIR, and imposes special requirements on the beam energy, intensity, emittance and time structure, beyond the standard range of the FAIR accelerators [1]. The beam preparation scheme at FLAIR presently involves three decelerators (see Fig. 1): one magnetic synchrotron, the LSR, the electrostatic synchrotron USR (up to now a unique design regarding the parameters and functionality [2]), the linac-based HITRAP decelerator currently being commissioned at GSI [3] and diverse schemes of particle stopping and cooling in different traps. Together with more than 10 different planned experimental areas, the facility will be a combination of machines and experiments, requiring an elaborate beam transport system which permits a certain degree of parallel operation for the experiments.
