cDVAE: VAE-guided diffusion for particle accelerator beam 6D phase space projection diagnostics
A Scheinker - Scientific Reports, 2024 - nature.com
Imaging the 6D phase space of a beam in a particle accelerator in a single shot is currently
impossible. Single shot beam measurements only exist for certain 2D beam projections and …

Pulsed Electron Lenses for Space Charge Mitigation
To produce ultimate high-brightness hadron beams, synchrotrons need to overcome a most
prominent intensity limitation, ie, space charge. This Letter characterizes the potential of …

Machine learning surrogate for charged particle beam dynamics with space charge based on a recurrent neural network with aleatoric uncertainty
In this work, we develop a machine learning (ML) model with aleatoric uncertainty for the low
energy beam transport (LEBT) region of the LANSCE linear accelerator in which we model …

cDVAE: Multimodal generative conditional diffusion guided by variational autoencoder latent embedding for virtual 6D phase space diagnostics
A Scheinker - ar** of transverse head-tail instabilities with a pulsed electron lens in hadron synchrotrons
A pulsed electron lens produces a betatron tune shift along a hadron bunch as a function of
the longitudinal coordinates, which is a longitudinal detuning. An example of transverse …

Beam-based Identification of Magnetic Field Errors in a Synchrotron using Deep Lie Map Networks
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 …

Space Charge and Future Light Sources
It is a truth universally acknowledged, that space charge effects in ultrarelativistic electron
storage rings are irrelevant due to the steep inverse dependence of their strength on the …
