Abstract
A fine tuning has been performed for RF phase and amplitude of SDTL (Separate-type Drift Tube Linac) station in the beam commissioning of J-PARC LINAC. A phase-scan method is adopted to carry out the tuning. An adequate set-point is determined by matching measured absolute beam energy with those from a modeling. The tuning goal is satisfied using this method, which required within 1deg for phase and 1% for amplitude. This paper presents detail procedures of RF tuning of SDTL.
