Historically, the values of the field amplitudes and phases of the side-coupled, 805-MHz LANSCE linac modules are maintained using a well-known delta-t tuning procedure*. Time-of-flight measurements of the proton beam energy are now also being used to confirm and improve the overall control of the energy ramp along the linac. The time-of-flight method uses measurements of the difference in RF phases measured as the beam passes installed delta-t pickup loops. A newly developed chassis to control the 3D position of the beam centroid is used. Details of the procedure and results of measurements are presented.
