Transition crossing of proton beams in SIS100
[arXiv:2302.02781]
arXiv 22 p. ()
The proton cycle in the SIS100 synchrotron is designed to deliver single bunches with $2\times10^{13}$ particles at 29 GeV. During the cycle beam dynamics near transition energy have to be analyzed to avoid a significant emittance blow-up. [...]

Multipass beam breakup instability countermeasures in energy recovery linacs
Technical University of Darmstadt 127 p. () [10.26083/TUPRINTS-00022915] = Dissertation, Technical University of Darmstadt, 2022
The multipass regenerative multibunch beam breakup instability is specific to recirculating linacs (linear accelerators) and energy recovery linacs operating in continuous wave mode where particle bunches pass multiple times through the same superconducting RF cavities with extremely high quality factor. Parasitic electromagnetic modes excited in the cavities can affect bunch dynamics in such a way, that on its subsequent passes it excites the modes further and a positive feedback loop is formed. [...]

Absence of Structure Resonances in SIS100 Tune Quadrant for Heavy Ion Fast Extraction
[ ; arXiv:2204.06435]
9 p ()
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 subsequent beam loss. This report discusses the absence of structure resonances for heavy-ion operation in SIS100 in the tune quadrant foreseen for the fast extraction mode, 18.5 < Qx,y < 19 . [...]

Impact of Field Errors of Quadrupole Units on Beam Losses at SIS100 Injection
[arXiv:2204.06441]
9 p ()
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 of the first 10 series quadrupole units. They are compared to the (stamped) First-of-Series quadrupole unit #2..
