Super Heavy Experimental Ring (SHER) is one of the rings of the next
accelerator complex High Intensity Heavy Ion Accelerator Facility (HIAF) at
IMP[4]. Here, present ideas of the lattice design for the operation of the
large acceptance ring are presented. The SHER ring has to be optimized for
e-cooling and the lattice is designed for different modes. First of all, it is
designed in the so called isochronous mode as time-of-flight mass spectrometer
for short-lived secondary nuclei. Secondly, SHER can also be used to be a
storage ring for collecting and cooling the secondary rare isotope beams from
the transport line. In order to fulfil it's purpose, the ion optics can be set
to different ion optical modes
