Beam loading compensation in the rf cavities is a key for acceleration of high-intensity beams in the 3 GeV rapid cycling synchrotron (RCS) of the Japan Proton Accelerator Research Complex (J-PARC). Since we employ wideband magnetic alloy rf cavities for the J-PARC RCS and the wake voltage contains several harmonics. multiharmonic beam loading compensation is required. The multiharmon... https://parisnaturalfoodes.shop/product-category/org-sambucus/
