Abstract

A comparison of beam loss in the superconducting part (SCL) of the Spallation NeutronSource (SNS) linac for H- and protons is presented. During the experiment thenominal beam of negative hydrogen ions in the SCL was replaced by a proton beam created byinsertion of a thin stripping carbon foil placed in the low energy section of the linac.The observed significant reduction in the beam loss for protons is explained by adomination of the intra beam stripping mechanism of the beam loss for H-. The details ofthe experiment are discussed, and a preliminary estimation of the cross section of thereaction H- + H- -> H- + H0 + e ispresented. Earlier, a short description of these studies was presented in [1]. Copyright
