ISIS, the pulsed neutron spallation source located at the Rutherford Appleton Laboratory (UK), currently delivers a mean beam power of ∼0.2 MW to target. A 70 MeV H- linear accelerator feeds into a 50 Hz, 800 MeV proton synchrotron, accelerating up to 3×1013 protons per pulse. Potential injection scheme upgrades, aiming to raise average beam power towards 0.5 MW with a new 180 MeV linear accelerator, are presently being studied [1]. This paper highlights recent results from temperature studies of double layer carbon foils, suitable for injection at 180 MeV into ISIS, using ANSYS. Experimental results from KEK were used to benchmark models and the variation of temperature as a function of foil separation was investigated. Copyright © 2012 by IEEE.
