SPICE features a permanent rare-earth magnetic lens to collect and direct internal conversion electrons emitted from nuclear reactions to a thick, highly segmented, lithium-drifted silicon detector. This arrangement, combined with TIGRESS, enables in-beam $\\gamma$-ray and internal conversion electron spectroscopy to be performed with stable and radioactive ion beams.
