H- injection studies for the Fermilab Proton Driver

Details are given of a study of the H^- injection scheme proposed for the Fermilab Proton Driver, with particular reference to its possible use as part of a neutrino factory. Both longitudinal and transverse aspects have been covered. In the longitudinal plane, a continuous sequence of parameters has been found that generates the longitudinal emittance required by the design, with very low particle loss. Transversely, repeated computer simulations of nonlinear space charge effects have led to re-assessment of the tunes and method of phase space painting. The paper describes the codes used in the modelling and the general approach taken to optimise the overall scheme
