  The ISIS Facility at the Rutherford Appleton Laboratory in the UK produces intense neutron and muon beams for condensed matter research. It operates at 50Hz accelerating beam via a 70 MeV H linac and an 800 MeV proton synchrotron, delivering a mean beam power of 0.2 MW. As an initial step towards megawatt operations at ISIS, a study of replacement of the existing injector with a new 180 MeV H linac has recently been completed. This could enable an increase in beam power to approximately 0.5 MW. The ISIS Facility at the Rutherford Appleton Laboratory in the UK produces intense neutron and muon beams for condensed matter research. It accelerates 3×1013 protons per pulse (ppp) at 50 Hz through a 70 MeV H− linac and an 800 MeV proton synchrotron, delivering a mean beam power of ~0.2 MW. A favoured first step to upgrade ISIS towards the megawatt regime is replacement of the linac with a new 180 MeV injector described in [1]. Studies of this upgrade, which aims to increase mean beam power up to 0.5 MW are outlined in [2]. This paper reports on recent development of the designs including the injection septum, dipole power supplies and detailed tracking of partially stripped foil products.
