Title	Space charge loss mechanisms associated with half integer resonance on the ISIS synchrotron
Contributors	CM Warsop (STFC Rutherford Appleton Lab.), DJ Adams (STFC Rutherford Appleton Lab.), BG Pine (STFC Rutherford Appleton Lab.)
Abstract	ISIS is the spallation neutron source at the Rutherford Appleton Laboratory in the UK. Operation centres on a 50 Hz proton synchrotron, which accelerates ~3E13 ppp from 70 to 800 MeV, corresponding to beam powers of 0.2 MW. Beam loss limits operational intensity, and a main contributing mechanism is the action of half integer resonance under high space charge. Progress on studies using particle in cell simulations to explore the evolution of envelope motion, associated 2:1 parametric halo, and growth of particles from the outer core is presented. Comparisons are made with relevant theoretical models by studying the simplified 4D coasting beam case.
