Hyperfine structure measurements of the neutron-deficient indium (Z=49) isotopes, approaching the heaviest self-conjugate doubly-magic nucleus 100Sn, have been performed using collinear resonance ionization spectroscopy. These measurements provide an important benchmark in the development of many-body methods, which are now able to predict properties around the Z=N=50 shell-closures. Preliminary results from the run will be described, alongside a description of the CRIS experiment and an outline of development plans for the long-shutdown.
