Abstract :
The 1.5 GeV (proton) booster synchrotron nearing completion at the AGS (Alternating Gradient Synchrotron) will get its 200 MeV beam from the linac, via a 34.9 m-long linac-to-booster transport line (LTB). A schematic layout of the LTB is shown. The four dipoles, which are identical and are operated in series, provide a 126 degrees bend in the line. The authors employed three strategies for implementing control of the trajectory, namely, (1) a global correction, (2) a local correction, and (3) a zeroing correction. These, as well as their implementation, are discussed. Operating experience obtained from early commissioning runs are given. The hardware and software implementations are described.<>
