After commissioning of the radioactive beam experiment at ISOLDE (REX-ISOLDE) first series of physics experiments in 2002 and 2003 have been performed. The REX-ISOLDE charge state breeder adjusts the charge-to-mass ratio of isotopes from all over the nuclear chart to the LINAC requirements. A variety of isotopes from different mass regions of the nuclear chart have been charge bred with REXEBIS to the required A/q < 4.5. A variety of tests with REXTRAP, REXEBIS and the LINAC structures have been done, in order to study the beam parameters, transmission efficiency and upgrade options. The LINAC now consists of six resonators and one re-buncher cavity. The beam energy, which can be delivered towards the target areas, can be varied between 0.8 and 2.2. An additional boost to 3 MeV/u is now possible because of the upgrade with a 202.56 MHz IH-cavity developed for the MAFF project. In addition experiment using beams from the RFQ at 0.3 MeV/u have been performed for solid state physics experiments. The present status of the projects and the commissioning measurements will be presented.
