Radioactive ion beams from many chemical elements are produced at ISOLDE and more than 1000 Radioactive Ion Beams (RIBs) are available for the users.  With a Carbon nanotube target the element boron could be produced as a RIB for the first time and the isotope ⁸B (T_1/2=770 ms) could be observed. With this addition to the palette of ISOLDE beams the Facility can now provide beams from 74 chemical elements to the user community.
