Beam Loss Studies for the 2-MW LBNE Proton Beam Line
- Fermilab
Severe limits are required for allowable beam loss during extraction and transport of a 2.3 MW primary proton beam for the Long Baseline Neutrino Experiment (LBNE) at Fermilab. Detailed simulations with the STRUCT and MARS codes have evaluated the impact of beam loss of 1.6e14 protons per pulse at 120 GeV, ranging from a single pulse full loss to sustained small fractional loss. It is shown that localized loss of a single beam pulse at 2.3 MW will result in a destructive event: beam pipe failu re, damaged magnets and high levels of residual radiation inside the tunnel. A sustained full beam loss would be catastrophic. Acceptable beam loss limits have been determined and robust solutions developed to enable efficient proton beam operation under these constraints.
