Design Guideline for Minimizing Space-Charge-Induced Emittance Growth
Chuan Zhang
Space-charge-induced emittance growth is a big con-cern for designing low energy and high intensity linacs. The Equipartitioning Principle was introduced to mini-mize space-charge-…
Realizing long radio-frequency quadrupole accelerators with multiple shorter and independent cavities
Chuan Zhang, Holger Podlech, Eugene Tanke
It is well known that the tuning of a long radio-frequency quadrupole accelerator is demanding. This study investigated how to realize efficient long RFQ accelerators with multiple…
An efficient solution for accelerating very high intensity beams in the low and medium energy regime
Chuan Zhang, Holger Podlech, Ulrich Ratzinger +1
Taking advantage of the 0° synchronous phase, the KONUS ("Combined 0° Structure" translated from German "Kombinierte Null Grad Struktur") beam dynamics strategy enables long accele…
Design approach for modern high-current, radio-frequency quadrupole accelerators with low emittance transfer
Chuan Zhang, Holger Podlech
Radio Frequency Quadrupole (RFQ) accelerators often need to face the challenges of space charge effects from high beam currents. This study investigated how to reach RFQ beam dynam…
Frequency Jump at Low Energies
Chuan Zhang, Holger Podlech
One or more radio-frequency jumps are usually necessary for realizing a >= 100 AMeV/u proton or ion driver linac. Typically, such jumps happen in the range of \b{eta} = 0.2-0.6 bet…
