    High field concentration and magnetothermal stability are critical considerations when designing and fabricating magnetic lenses made from a stack of bulk high-temperature superconducting (HTS) material. In a previous study, we investigated a GdBCO magnetic lens for use as a compact high-field superconducting magnet, but it cracked due to a high flux jump. In the present study, we investigate the magnetic performance of an improved GdBCO lens. This new lens had almost the same dimensions as the previous one, but it was impregnated with epoxy resin to prevent it breaking. The impregnated lens exhibited superior stability and magnetic properties, making it promising for use in a compact magnet system. A maximum field of 13 T was obtained at 20 K with no flux jump.
