Topic : Development of high field in-vacuum permanent magnet wiggler for high intensity hard x-ray generation

  

 Scope  

                        In-vacuum permanent magnet wiggler is an insertion device used for high intensity hard x-ray generation in the modern synchrotron radiation machine. The development of this device incorporates various aspects of knowledge including synchrotron radiation generation, magnetic field calculation and measurement, magnet fabrication, vacuum system design, high precision mechanical and control system, etc. The aim of the project is to produce a prototype in-vacuum wiggler used for the 3 GeV synchrotron machine. Several tools required for the project are available at the Synchrotron Light Research Institute (Public Organization), such as Mathematica and Radia software for magnetic field simulation. Helmholtz coil, flip coil, and hall probe for magnetic field measurement. Computer and software for engineering drawing and simulation of heat load/structural deformation. During the research, the student will develop variety of skills required to build the in-vacuum permanent magnet wiggler. This includes physics and engineering of synchrotron radiation generation. Magnetic field system starting from the design, simulation, fabrication, and measurement. Ultra-high vacuum system and high precision assembly and control of the in-vacuum permanent magnet wiggler device.
