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…
Generalized Kapchinskij-Vladimirskij Distribution and Beam Matrix for Phase-Space Manipulations of High-Intensity Beams
Moses Chung, Hong Qin, Ronald C. Davidson +2
In an uncoupled linear lattice system, the Kapchinskij-Vladimirskij (KV) distribution, formulated on the basis of the single-particle Courant-Snyder (CS) invariants, has served as…
In Situ Measurement of Mechanical Vibrations of a 4-Rod RFQ at GSI
P. Gerhard, L. Groening, K. -O. Voss
A new 4-rod RFQ was commissioned at the UNILAC in 2009, it went into operation in 2010. At high rf amplitudes strong modulations of the rf reflection emerge. They are attributed to…
Experimental Proof of Adjustable Single-Knob Ion Beam Emittance Partitioning
L. Groening, M. Maier, C. Xiao +7
The performance of accelerators profits from phase space tailoring by coupling of planes. The previously applied techniques swap the emittances among the three planes but the set o…
