8 GeV H- ions: Transport and injection

Fermilab is working on the design of an 8 GeV superconducting RF H- linac called the Proton Driver. The energy of H- beam will be an order of magnitude higher than the existing ones. This brings up a number of technical challenges to transport and injection of H- ions. This paper will focus on the subjects of stripping losses (including stripping by blackbody radiation, field and residual gas) and carbon foil stripping efficiency, along with a brief discussion on other issues such as Stark states lifetime of hydrogen atoms, single and multiple Coulomb scattering, foil heating and stress, radiation activation, collimation and jitter correction, etc
