Overcoming Intrinsic Spin Resonances by Using an Rf Dipole

iv To my parents and my family v Acknowledgments This work could not come out without help, support and collaborative eeort from many people. Whatever mention I can make of them here can not match their true contributions and my deep appreciation. First of all, I would like to acknowledge my thesis advisor, Prof. S.Y. Lee, for his earnest guidance, inculcation and continued encouragement. As an excellent teacher, he intrigued my great interest in accelerator physics and innuenced me with his scrupulous and assiduous attitude. I am specially grateful to my two supervisors at Brookhaven AGS, Dr. T. Roser and Dr. M. Syphers. Their enlightening guidance, helpful advice and tremendous support have helped me nd my way through mazes that had to be traversed in the course of my research work. I feel so fortune to have them as mentors. I also sincerely thank Dr. A. Yokosawa who gave me this opportunity to work as a guest graduate student of Argonne National Laboratory. Their invaluable suggestions, insights in high energy physics and accelerator physics and constant support have substantially beneeted me on my thesis work I also owe an ongoing debt of gratitude to all the E880 collaborators who had made the successful E880 experiments happen. In particular, I would like to thank Dr. L. for their enormous help, suggestions and fruitful discussions. The success of the experiments also can not be separated from the tremendous help from engineers R. Sanders who designed and tested the resonant driving circuit of the AGS RF dipole, Ann Dunbar who helped in constructing and testing the magnet, G. Smith who also helped us vi with BPM system, also thank the AGS chairperson, Dr. D. I. Lowenstein, for giving me this wonderful chance to work in the AGS and providing me an excellent accommodation. At last, I thank all the AGS personnel who provided me with such a friendly and cooperative atmosphere. Again, I would like to thank my advisor committee members Prof. who have also helped me in many ways. In addition, thanks are due especially to my present and former fellow colleagues at My two years in Bloomington have let me meet so many wonderful people, the professors whose classes I enjoyed and am beneeted, the department secretaries, B. Carson and J. Dizer who gave me their generous help and assistance especially when I was oo campus. I also made a lot …
