Conceptual Design Report for FAIR Computing
Johan Messchendorp, Mohammad Al-Turany, Volker Friese +10
This Conceptual Design Report (CDR) presents the plans of the computing infrastructure for research at FAIR, Darmstadt, Germany. It presents the computing requirements of the vario…
Measurement of the Orbit Response Matrix for the SIS18 Doublet Optics
Victoria Isensee, Conrad Caliari, Adrian Oeftiger
This report describes the setup and results of a 2024 experiment on beam-based measurement of the Orbit Response Matrix (ORM) for the GSI Heavy Ion Synchrotron SIS18, characterisin…
Beam-based Identification of Magnetic Field Errors in a Synchrotron using Deep Lie Map Networks
Conrad Caliari, Adrian Oeftiger, Oliver Boine-Frankenheim
We present the first experimental validation of the Deep Lie Map Network (DLMN) approach for recovering both linear and non-linear optics in a synchrotron. The DLMN facilitates the…
Pulsed Electron Lenses for Space Charge Mitigation
Adrian Oeftiger, Oliver Boine-Frankenheim
To produce the intense, high-quality hadron beams required by future nuclear and high-energy physics experiments, synchrotrons need to overcome a most prominent intensity limitatio…
Identification of Magnetic Field Errors in Synchrotrons based on Deep Lie Map Networks
Conrad Caliari, Adrian Oeftiger, Oliver Boine-Frankenheim
Magnetic field errors pose a limitation in the performance of synchrotrons, as they excite non-systematic resonances, reduce dynamic aperture and may result in beam loss. Their eff…
Characterization and minimization of the half-integer stop band with space charge in a hadron synchrotron
Dmitrii Rabusov, Adrian Oeftiger, Oliver Boine-Frankenheim
In any hadron synchrotron, the half-integer resonance is among the strongest effects limiting the achievable maximum beam intensity. The heavy-ion superconducting synchrotron SIS10…
Impact of Field Errors of Quadrupole Units on Beam Losses at SIS100 Injection
Adrian Oeftiger
This report discusses heavy-ion beam losses due to the nominal transverse space charge and the field imperfections in SIS100 during accumulation based on recent cold measurements o…
Absence of Structure Resonances in SIS100 Tune Quadrant for Heavy Ion Fast Extraction
Adrian Oeftiger
The understanding and avoidance of space charge induced resonances is of utmost importance for long storage times in synchrotrons, as they can lead to halo generation and subsequen…
Simulation Study of the Space Charge Limit in Heavy-ion Synchrotrons
Adrian Oeftiger, Oliver Boine-Frankenheim, Vera Chetvertkova +3
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. Beam losses due to space…
Proof-of-principle direct measurement of Landau damping strength at the Large Hadron Collider with an anti-damper
S. A. Antipov, D. Amorim, N. Biancacci +5
Landau damping is an essential mechanism for ensuring collective beam stability in particle accelerators. Precise knowledge of how strong Landau damping is, is key to making accura…
Parallelisation of PyHEADTAIL, a Collective Beam Dynamics Code for Particle Accelerator Physics
Adrian Oeftiger
The longitudinal tracking engine of the particle accelerator simulation application PyHEADTAIL shows a heavy potential for parallelisation. For basic beam circulation, the tracking…
Flat Bunches with a Hollow Distribution for Space Charge Mitigation
Adrian Oeftiger, Hannes Bartosik, Alan James Findlay +2
Longitudinally hollow bunches provide one means to mitigate the impact of transverse space charge. The hollow distributions are created via dipolar parametric excitation during acc…
