Description

The Side-Coupled Linac (SCL) section of the FNAL Linac accelerates the 20-25 mA H- beam from 116 MeV to 402 MeV in 7 modules. All major components of this section are re-calibrated using beam-based measurements. Module gradients and phases are determined from the phase scans. Longitudinal bunch parameters at the entrance of the section are reconstructed using a Bunch Shape Monitor. Calibrations of quadrupoles and correctors are improved using differential trajectories. Initial beam conditions are deduced from quadrupole scans. Using the model, the beam envelope along the SCL section is predicted using the TraceWin code and compared with measurements by wire scanners.
