Halo Collimation of Light and Heavy Ions in the FAIR Synchrotron SIS100 — •Ivan Prokhorov1, Ivan Strasik2, and Oliver Boine-Frankenheim1,2 — 1TU-Darmstadt, Darmstadt, Germany — 2GSI, Darmstadt, Germany
The halo collimation system in the FAIR synchrotron SIS100 is needed to prevent an interception of the beam halo particles by the accelerator structure. The two-stage betatron collimation system is considered for operation with protons and fully-stripped ions. An adequate numerical simulation of the collimation system performance taking into account a precise description of the following processes: 1) particle scattering by the primary collimator; 2) inelastic nuclear interaction of the ions with the collimator foil; 3) momentum losses during the interaction with the collimator foil; 4) multi-turn tracking of the particles with the collimation optics included.
The concept of the halo collimation, the current status of research and future plans are presented. Scattering processes and momentum losses were analytically estimated for various ion species and energies; analytical results were compared with the numerical simulations by the ATIMA code. Preliminary results of particle tracking using MAD-X code were obtained.
