Abstract

In the beam commissioning of J-PARC (Japan Proton Accelerator Research Complex) Linac, the RF amplitude and phase tuning has been performed for its DTL (Drift Tube Linac). The tuning has been performed with a "phase- scan" method, monitoring the output beam energy from each DTL tank. Comparing the obtained phase dependence of the output beam energy with those from the modeling, we have tuned the RF phase and amplitude for DTL tanks mostly within the required tuning accuracy of 1 deg in phase and 1 % in amplitude, although further analysis is required to quantitatively evaluate the achieved tuning accuracy.
