Longitudinal tune-up of the SSC drift-tube and coupled cavity linac sections

摘要

The drift-tube and coupled cavity sections of the SSC (Superconducting Super Collider) linac will accelerate H/sup -/ beam from 2.5 MeV to 70 MeV, and from 70 MeV to 600 MeV, respectively. Two different procedures, namely the phase-scan method and the Delta -t method, have been in use for setting RF phase and amplitude in existing linac structures. Applicability of these two techniques for longitudinal commissioning and subsequent tuning are examined in context to the SSC linac sections.
