Emittance Growth Due to Steering Errors for the 8 GeV AP3-P1 Lattice

PDF Version Also Available for Download.

Description

During 8 GeV antiproton transfers between the Accumulator to the Main Injector, the antiprotons must travel through four separate beam lines, AP3, AP1, P2, and P1. The AP1, P1, and P2 transfer lines are also used for 120 GeV antiproton production so that many of the magnet strings must accommodate a large range of excitation current. This note will quantify the relationship between emittance dilution for 8 GeV antiprotons injected into the Main Injector and variations in the excitation currents of the bending magnets.
