Well known in the community of high-intensity linear accelerators, the transport code
TraceWin is able to simulate a beam from the source to the target using either simple linear …

Understanding the 3D collective long-term response of beams exposed to resonances is of
theoretical interest and essential for advancing high intensity synchrotrons. This study of a …

An extensive experimental study is performed to confirm fundamental resonance bands of
an intense hadron beam propagating through an alternating gradient linear transport …

The aim of this study is to make the parameter space of zero-current phase advance greater
than 90° available to the high-intensity linear accelerator (linac) design and operation, which …

This paper addresses the generalization of the single-particle betatron resonance condition
derived by Courant and Snyder more than a half century ago. A two-dimensional resonance …

Parametric resonances of beam eigenmodes with a periodic focusing system under the
effect of space charge—also called structural instabilities—are the collective counterparts to …

The space-charge driven envelope instability can be of great danger in high intensity
accelerators and was studied using a two-dimensional (2D) envelope model and three …

In high intensity linacs emittance exchange driven by space charge coupling may lead to the
well-known “equipartitioning” phenomenon if the stop band at σ‖= σ⊥ is crossed at …

For injection of beams into circular machines with different horizontal and vertical emittance
acceptance, the injection efficiency can be increased if these beams are flat, ie, if they …

The well-known envelope instability or the second order even collective mode [I. Hofmann,
Phys. Rev. E 57, 4 (1998)] and the fourth order resonance 4 σ= 360° due to the nonlinear …
