Low Beta, Normal Conducting Cavities
Lars Groening
The contribution is on issues being especially related to normal conducting cavities operating at non-relativistic beam energies. Various types of cavities are introduced w.r.t. th…
Periodic solution for transport of intense and coupled coasting beams through quadrupole channels
Chen Xiao, Lars Groening
Imposing defined spinning to a particle beam increases its stability against perturbations from space charge~[Y.-L.~Cheon et al., Effects of beam spinning on the fourth-order parti…
Particle beam eigen-emittances, phase integral, vorticity, and rotations
L. Groening, C. Xiao, M. Chung
Particle beam eigen-emittances comprise the lowest set of rms-emittances that can be imposed to a beam through symplectic optical elements. For cases of practical relevance this pa…
Refining the evaluation of eigen-emittances measured by the dedicated four-dimensional emittance scanner ROSE
C. Xiao, X. N. Du, L. Groening +1
A dedicated device to fully determine the four-dimensional beam matrix, called ROSE (ROtating System for Emittance measurements) was successfully commissioned. Results obtained wit…
Relation between particle beam eigen-emittances and canonical vorticity flux
Lars Groening, Moses Chung
Particle beams provided by accelerators occupy a finite volume of the four dimensional transverse phase space. The latter is spanned by the four degrees of freedom, i.e., horizonta…
Extension of Busch's Theorem to Particle Beams
L. Groening, M. Chung, C. Xiao
In 1926, H. Busch formulated a theorem for one single charged particle moving along a region with a longitudinal magnetic field [H. Busch, Berechnung der Bahn von Kathodenstrahlen…
