Other AbstractThe work of this dissertation is mainly about the key device of synchrotron radiation facility, including: the investigations on the theories and numerical methods of undulator spontaneous radiation, studies on magnetic structure of the new types of undulators and their radiation properties, and some calculations about the undulators for beamlines of Shanghai Synchrotron Radiation Facility (SSRF) project. Chapter One of the dissertation introduces the characters of synchrotron radiation, brief history of synchrotron radiation facility and undulator. It also introduces the research results about the undulator theories and techniques at home and aboard. Chapter Two introduces the theories of undulator spontaneous radiation. It presents analytic formulae to calculate most properties of undulator spontaneous radiation. Chapter Three introduces the simulation methods of undulator spontaneous radiation and the characters of the calculating program URCP. Chapter Four presents the calculation for the radiation properties of undulators in SSRF, including the optimization of the undulator parameter for the macromolecular complexes beamline. Chapter Five introduces the elliptically polarized undulator (EPU), including magnetic structures of different types of EPUs, the radiation theory and properties of EPU, and a particular analysis of radiation properties of the tapered Apple-II undulator. Chapter Six introduces the tapered undulator. It presents the magnetic structure and radiation properties of different tapered undulator first. Then it introduces a new type of tapered undulator and its radiation properties. The practical magnetic structure is also discussed in this chapter. Chapter seven introduces the characters of the quasi-periodic undulator and two-harmonic undulator. A systemic method to study the undulator magnetic field and undulator spontaneous radiation spectrum is built. This method will benefit the Shanghai Synchrotron Radiation Facility (SSRF) project and the development of new techniques of synchrotron radiation facility.
