説明

<p>In the LLRF system of J-PARC LINAC, the two new digital control systems have been developed and updated for 324-MHz stations. One system utilizes a digitizer box and the existing cPCI analog boards, while the other system incorporates the μTCA.4 system including new analog boards. A stable accuracy of ±0.1% (peak-to-peak) in amplitude and ±0.1 deg. (pp) in phase has been achieved in the absence of beam. To leverage the capabilities of new systems, the open loop transfer functions were calculated. Additionally, an adaptive beam loading compensation system, which was not feasible with the previous digital control system, has been implemented.</p>
