Abstract :
One of the options considered for the SNS linac, to reduce the cost, was to lower the energy to 840 MeV and leave space in the tunnel for a future upgrade to 1.3 GeV either by adding cryo-modules or increasing the gradient in the SC linac. A linac energy other than 1.0 GeV will have an impact on the transfer line and accumulator ring. The energy impacts the location of the corrector cavity in the HEBT, the injection magnet, beam power, dE/dx, multiple scattering and H- stripping, neutron production at the target etc. These issues will be discussed, and changes required in the transfer lines and accumulator ring to accommodate lower energy beam are presented
