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…
A New Injection and Acceleration Scheme of Positrons in the Laser-Plasma Bubble Regime
Z. Y. Xu, C. F. Xiao, H. Y. Lu +15
A novel approach for positron injection and acceleration in laser driven plasma wakefield is proposed. A theoretical model is developed and confirmed through PIC simulation. One ri…
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…
Rotating system for four-dimensional transverse rms-emittance measurements
C. Xiao, M. Maier, X. N. Du +4
Knowledge of the transverse four-dimensional beam rms-parameters is essential for applications that involve lattice elements that couple the two transverse degrees of freedom (plan…
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…
Particle-In-Cell Simulation of RFQ in SSC - Linac
Xiao Chen, He Yuan, Yuan You-Jin +4
A 52MHz Radio Frequency Quadrupole (RFQ) linear accelerator (linac) is designed to serve as an initial structure for the SSC-linac system (injector into Separated Sector Cyclotron)…
