Topic : Studies of low-emittance beam injection efficiency of 4^th generation synchrotron light source

  

 Scope  

                        Modern synchrotron light sources have been designed in order to achieve low electron beam emittance resulting in high photon beam brightness particularly at X-ray wavelengths. 4th generation synchrotron light sources focus on design of storage rings based on multi-bend achromat (MBA) lattices which enables a reduction of electron a few orders of magnitude compared to 3rd generation synchrotron light sources. Electron beam motion in a storage ring is affected by dynamic effects leading to large amplitude oscillations. Dynamic aperture, which is the border accommodating electron beam stable orbits in a storage ring, is significant for determining electron beam injection efficiency and lifetime of stored electron beam. A challenge in the design of MBA storage rings is to achieve lower beam emittance with sufficient dynamic aperture. Beam injection into a low-emittance storage ring with low dynamic aperture has been extensively studied based on different beam injection schemes and techniques aiming to achieve high injection efficiency. This research covers both theoretical analysis and numerical simulations for the studies of beam injection. There are many codes for particle accelerator simulations available for beam injection simulations. Skills related to programing, numerical simulations, and particle beam dynamics should be built and developed in this study.
