Accelerator Physics

The Joint Universities Accelerator School 2024 features an accelerator design workshop. This published container provides the lattice design jupyter notebook, which contains the setup and exercises to design a particle collider, alongside with a working environment to run the notebook with all required software tools such as MAD-X.

Simulation results for beam loss in the FAIR SIS100 synchrotron for a comprehensive study on pulsed electron lenses for space charge mitigation. The affiliated manuscript 'Pulsed electron lenses for space charge mitigation' describing the study parameters is published on arxiv.org (https://arxiv.org/abs/2310.02365) and submitted for journal publication. [...]

To produce ultimate high-brightness hadron beams, synchrotrons need to overcome a most prominent intensity limitation, i.e., space charge. This Letter characterizes the potential of pulsed electron lenses in detailed 3D tracking simulations, key to which is a realistic machine and space charge model. [...]

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. [...]

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.
