Despite the more than 60-year old history of thick-target ISOL mass-separation facilities like ISOLDE, the extraction of the most refractory elements as radioactive ion beam has so far not been successful. In ordinary thick ISOL targets, their radioisotopes produced in the target are stopped within the condensed target material and have to diffuse through a solid material.
