Self-Stimulated Undulator Radiation and its Possible Applications [PDF]
, 2010 We investigated the phenomena of self-stimulation of incoherent emission from an undulator installed in the linear accelerator or quasi-isochronous storage ring.

Space charge dynamics in high intensity rings
Physical Review Special Topics. Accelerators and Beams, 1999 Uncontrolled beam losses due to space-charge-induced halo generation are a concern in high intensity rings, which are characterized by high beam intensities and low uncontrolled beam loss requirements.

Review of linear optics measurement and correction for charged particle accelerators
Physical Review Accelerators and Beams, 2017 Measurement and correction of charged particle beam optics have been a major concern since the advent of strong focusing synchrotron accelerators. Traditionally, particle colliders have led the development of optics control based on turn-by-turn beam ...

Stripping mechanisms and remediation for H^{-} beams
Physical Review Accelerators and Beams, 2021 Negative hydrogen ions are often used for injecting protons from linacs to storage rings via charge-exchange injection. In this process, the two electrons are stripped by a foil or laser to produce protons which can be merged with an existing beam ...

Physics-based deep neural networks for beam dynamics in charged particle accelerators
Physical Review Accelerators and Beams, 2020 This paper presents a novel approach for constructing neural networks which model charged particle beam dynamics. In our approach, the Taylor maps arising in the representation of dynamics are mapped onto the weights of a polynomial neural network.

Throbbing Beam Instabilities in Particle Accelerators and Storage Rings [PDF]
IEEE Transactions on Nuclear Science, 1967 Finite conductivity of the vacuum chamber wall can cause unstable coherent transverse oscillations of the center of charge and also oscillations of the transverse cross section of a beam of charged particles. The former case, which can be characterized by a dipole oscillation, has been studied extensively by others.

Ion-hose instability in a long-pulse linear induction accelerator
Physical Review Special Topics. Accelerators and Beams, 2003 The ion-hose instability is a transverse electrostatic instability which occurs on electron beams in the presence of a low-density ion channel. It is a phenomenon quite similar to the interaction between electron clouds and proton or positron beams in ...

Longitudinal Instabilities in Circular Accelerator and Storage Rings [PDF]
IEEE Transactions on Nuclear Science, 1981 The general problem of the longitudinal stability of bunched beams is reviewed. Although there is no general solution it is possible to identify regions in the frequency-risetime space where we can obtain approximate solutions. The collective oscillation frequency is written, and expressions for the effective coupling impedance are given for the high ...
