||
The recent progresses in the LLRF FPGA control system of the J-PARC LINAC will be presented in this paper, including 1) automatically switching the beam loading compensation in accordance with the different beam operation mode, 2) chopped beam compensation for the 972-MHz section, and 3) input rf-frequency tuning to match the rf cavities. All of those functions are realized by the FPGA. |
