    "abstract": "KEK electron linac was upgraded to 8 GeV for the KEK B-Factory (KEKB)\nproject. During the commissioning of the upgraded linac, even continuing SOR\nring injections, we had achieved a primary electron beam with 10-nC (6.24 x\n10^10) per bunch up to 3.7-GeV for positron generation. This could be\nclassified as one of the brightest S-band linac\u0027s.\n  Since the KEKB rings were completed in December 1998, those 3.5-GeV position\nand 8-GeV electron beams have been injected with an excellent performance.\nMoreover, we have succeeded in switching among the high-intensity beams for\nKEKB and beams for two SOR rings with sufficient reproducibility.\n  After the commissioning of the KEKB ring started, we have launched a project\nto stabilize the intensity and quality of the high-current beams furthermore,\nand have accomplished it investigating every conceivable aspect.",
