Title 1: Space-charge Simulation of Integrable Rapid Cycling Synchrotron

A1: Integrable optics is an innovation in particle accelerator design that enables strong nonlinear focusing without generating parametric resonances. Our preliminary simulation results indicate integrable optics enables an accelerator to sustain a high-intensity beam with strong non-linear focusing. The advantage of integrability can be combined with other features of modern ring design. We present an 8-GeV integrable rapid cycling synchrotron (iRCS) design that has long dispersion-free drifts, features six-fold periodicity, avoids transition crossing, corrects chromaticity with harmonically canceling sextupoles. Consequently, an iRCS replacement for the Fermilab Booster could enable the Main Injector to achieve multi-MW beam power for the long-baseline neutrino program. Experimental tests of the efficacy of integrable optics in controlling high-intensity beams will take place over the next several years at the Fermilab Integrable Optics Test Accelerator (IOTA) and the University of Maryland Electron Ring (UMER).

Title 2: The Energy Efficiency of High Intensity Proton Driver Concepts

A2: For MW class proton driver accelerators, the energy efficiency is an important aspect; the talk reviews the efficiency of different accelerator concepts including superconducting and normal conducting linacs, rapid cycling synchrotron, and cyclotron. The potential of these concepts for very high beam power is discussed. The talk is based on the result of the Proton Driver Efficiency Workshop organized by EuCARD2.
