SHER-HIAF ring lattice design

The Super Heavy Experimental Ring(SHER), which is one of the rings of the next accelerator complex High Intensity Heavy Ion Accelerator Facility(HIAF) at IMP, has to be optimized for e-cooling. Its lattice is designed for two modes: the first is the isochronous mode, which is a time-of-flight mass spectrometer for short-lived secondary nuclei, the second is the storage ring mode, which is used for collecting and cooling the secondary rare isotope beams from the transport line. In order to fulfil its purpose, the ion optics can be set to different ion optical modes.
