Beam quality and beam loss predictions with space charge for SIS100

The SIS100 synchrotron as a part of the new FAIR accelerator facility at GSI should be operated at the “space charge limit” for light and heavy-ion beams. Losses due to space charge induced resonance crossing should not exceed a few percent during a full cycle. Detailed magnet field measurements are...

Description
Summary:The SIS100 synchrotron as a part of the new FAIR accelerator facility at GSI should be operated at the “space charge limit” for light and heavy-ion beams. Losses due to space charge induced resonance crossing should not exceed a few percent during a full cycle. Detailed magnet field measurements are now available for 72 out of the total 108 main SIS100 dipole magnets. Particle tracking studies including nonlinear field errors up to 7th order in the main magnets together with different space charge models are performed. Because of the long time scales reduced space charge models are employed for tune scans. First comparisons with simulations using a self-consistent space charge solver are discussed as well as potential measures to further improve the options in tune space for the reference intensities and beyond.
