Achievement of ultralow emittance coupling in the Australian Synchrotron storage ring
Investigations into producing an electron beam with ultralow vertical emittance have been conducted using the Australian Synchrotron 3 GeV storage ring. A method of tuning the emittance coupling (ϵ_{y}/ϵ_{x}) has been developed using a machine model calibrated through the linear optics from closed o...
