| Notes | LI Song, ZHANG Junqiang, ZHANG Meng, ZHAO Minghua （1Shanghai Institute of Applied Physics, Chinese Academy of Sciences, Jiading Campus, Shanghai 201800, China;2University of Chinese Academy of Sciences, Beijing 100049, China） Background： Due to the existence of transient beam loading effect in cavity, the energy of the bunch head is higher than the other part in 15-MeV linear accelerator （LINAC） designed for thorium molten salt reactor （TMSR） photo-neutron source. This uneven distribution of energy leads to high energy spread, thus depresses transmission efficiency of beam. Purpose： This study aims to develop a digital feedforward compensation to reduce the influence of beam loading effect and decrease energy spread of the beam. Methods： The Field Programmable Gate Array （FPGA） programming language VHDL （Very-High-Speed Integrated Circuit Hardware Description Language） was used to design the feedforward module. This module was added to the original FPGA modules of low level radio frequency （LLRF） control syste |
