Description
In the ESS neutrino super beam (ESSnuSB) project, an efficient injection into the accumulator ring is required for minimizing beam loss during injection, reducing capital cost, and simplifying the overall project. To meet these requirements, the Liouvillian Injection Optimization (LIO) method has been developed for direct proton injection into the accumulator using a 4D multi-turn accumulation process without stripping. This method enables to paint both the horizontal and vertical phase-space simultaneously using a tilted septum. In this study, the LIO method has been investigated using the PyOrbit simulation code. The results demonstrate the method’s dependency to the lattice tune, the injected beam beta function, the close-orbit rout, and space-charge effects, which play a dominant role on the efficiency of the injection process. This work present the optimization of the method considering space charge effects, lattice nonlinearities, and considerations on its capabilities.
