【 摘 要 】

Measured beam parameters from the Main Injector are used to calculate the beam envelope from MI extraction to the Meson area. The primary beam is then transported to a straw-man experiment in the MP beamline. Secondary yields are also calculated for the MTest test beam. For this study, it was assumed that the A0 region was modified as per Switchyard in the Main Injector Era Technical Design Report, and that the cryogenic magnets in Switchyard had EPB type gaps. Under these assumptions, it is possible to transport 120 GeV/c protons from the Main Injector to the Meson and New Muon areas with minimal (on the order of 1%) scraping. Regarding the Meson area, this scraping occurs at the FSeps (which produce the three-way split to Meson). Regarding the New Muon area, the scraping occurs at the MuSeps, MuLams (both of which establish the Neutrino/Muon split), and the final focusing quadrupoles. Thus, multi-beam, high-intensity running to the Meson area is precluded, as is high intensity running to the New Muon area.
