	The ISIS Facility at the Rutherford Appleton Laboratory in the UK produces intense neutron and muon beams for condensed matter research. It operates at 50 Hz accelerating 3x10¹³ protons per pulse via 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. Studies of this upgrade, which aims to increase mean beam power up to 0.5 MW are continuing. This paper summarises designs for a new injection region including beam dynamics and related hardware.

	The ISIS synchrotron forms part of the accelerator chain for the Spallation Neutron Source at RAL, UK. The synchrotron is an 800 MeV, 50Hz , RCS accelerating ~2.8·10¹³ protons per cycle. Beam loss is localized in two super periods of the ring using a system of collimators. The injection and acceleration processes, vacuum vessels and collimation systems have been modeled using the particle tracking code ORBIT. This paper presents simulation results in comparison to measurements of longitudinal profiles and beam loss.
