1. Setting momentum for 1-pass. Since the expected beam energy is E = 58.5(linac) + 1041(1-pass) = 1099.5 MeV we put the spectrometers at L = 1.0995 GeV R = 1.0957 GeV This is scaling from 3-pass result for which the L-arm was almost exactly at the calculated E' and R-arm was 0.35% lower. 2. Put target to empty target position to be safe.
