Longitudinal phase space manipulation using double emittance exchange to generate multi-color X-ray
J. Seok, G. Ha, J. Power +1
Generating temporally separated two X-ray pulses or even two pulses with different colors has been pursued for various X-ray experiments. Recently, this concept is extended to gene…
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…
Mitigation of Space-Charge-Driven Resonance and Instability in High-Intensity Linear Accelerators via Beam Spinning
Yoo-Lim Cheon, Seok-Ho Moon, Moses Chung +1
For modern high-intensity linear accelerators, the well-known envelope instability and recently reported fourth-order particle resonance impose a fundamental operational limit (i.e…
Proton beam defocusing in AWAKE: comparison of simulations and measurements
A. A. Gorn, M. Turner, E. Adli +96
In 2017, AWAKE demonstrated the seeded self-modulation (SSM) of a 400 GeV proton beam from the Super Proton Synchrotron (SPS) at CERN. The angular distribution of the protons defle…
Experimental Study of Wakefields Driven by a Self-Modulating Proton Bunch in Plasma
M. Turner, P. Muggli, the AWAKE Collaboration
We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growt…
Linear Beam Stability in Periodic Focusing Systems:Krein Signature and Band Structure
Moses Chung, Yoolim Cheon, Hong Qin
The general question of how a beam becomes unstable has been one of the fundamental research topics among beam and accelerator physicists for several decades. In this study, we rev…
