The production of medical radioisotopes for theranostics is essential for nuclear medicine developments. A research program is ongoing at the 18 MeV Bern medical cyclotron, where a solid target station is in operation together with a 6.5 m Beam Transfer Line (BTL) ending in a separate bunker. To irradiate compressed powder pellets, novel target coins were conceived and realized together with methods to assess the beam energy and the production cross-sections. The activity at the end of the beam (EOB) is measured with a 1 cm3 CdZnTe detector. An ultra-compact active irradiation system based on a novel focusing and steering magnet and two-dimensional beam detectors is under development. Results on 43Sc, 44Sc, 47Sc, 61Cu, 64Cu, 68Ga, 155Tb, 165Er and 165Tm production are presented.
