Demonstration of a novel phase space painting method in a coupled lattice to mitigate space charge in high-intensity hadron beams
Nicholas J. Evans, Austin Hoover, Timofey Gorlov +1
Multi-turn charge-exchange injection is the primary method of creating high-intensity hadron beams in circular accelerators, and phase space painting during injection enables tailo…
High-dimensional maximum-entropy phase space tomography
Austin Hoover
Reconstructing 4D or 6D phase space distributions from 1D or 2D measurements is a challenging inverse problem encountered in particle accelerators. Entropy maximization is an estab…
N-dimensional maximum-entropy tomography via particle sampling
Austin Hoover
We propose a modified maximum-entropy (MENT) algorithm for six-dimensional phase space tomography. The algorithm uses particle sampling and low-dimensional density estimation to ap…
Four-dimensional phase space tomography from one-dimensional measurements of a hadron beam
Austin Hoover
In this paper, we use one-dimensional measurements to infer the four-dimensional phase space density of an accumulated proton beam in the Spallation Neutron Source (SNS) accelerato…
High-dimensional maximum-entropy phase space tomography using normalizing flows
Austin Hoover, Jonathan C. Wong
Particle accelerators generate charged-particle beams with tailored distributions in six-dimensional position-momentum space (phase space). Knowledge of the phase space distributio…
