ISIS is the world's most productive spallation neutron source, at the Rutherford Appleton Laboratory in the UK. Presently it runs at beam powers of 0.2 MW, with upgrades in place to supply increased powers for the new Second Target Station. Injection of beam into the present ISIS ring at higher energy than from the existing 70 MeV linac has significant potential to increase intensity as a result of reduced space charge and optimised injection. This paper outlines studies for this upgrade option, which include achieving a practical injection system at higher energy in the present ring, ensuring the modified longitudinal and transverse beam dynamics are possible with low loss at higher intensity and achieving low loss and loss control to allow for the increased activation at higher energy.
