iThemba LABS has been in operation for more than 30 years and is now at a stage at which refurbishment and ' in some cases ' replacement of the infrastructure and critical components is required. The replacement and refurbish-ment of the cooling system, which include the cooling tow-ers and chillers, the 4.4-MVA uninterruptable power sup-ply batteries and other critical components, are discussed. Progress with a facility for low-energy radioactive ion beams will be reported on. A proposal to remove radioiso-tope production from the separated sector cyclotron (SSC) and the production of the future radioisotopes with a com-mercial 70-MeV cyclotron to make more beam time avail-able for nuclear physics research with the SSC will also be discussed. Developments on our electron cyclotron reso-nance ion sources, the PIG ion source and low-level digital RF control system have also been carried out.
