Abstract :
A scheme for injection into the FODO cell of the National Spallation Neutron Source (NSNS) accumulator ring is discussed. A 400 μg/cm2 carbon foil is chosen for a high stripping efficiency and for heating of the foil consideration. Additional schemes to reduce losses due to nuclear and Coulomb scattering at the foil are discussed. Subsequent loss from magnetic field ionization of the residual H0 component is estimated to be small comparable to nuclear loss. A method for sweeping and collecting the stripped electrons from the foil is presented
