ReA was integrated in 2013 into the Coupled Cyclotron Facility providing unique low-energy rare isotope beams. After the fast rare isotopes are stopped in a gas stopping system, mass separated and their charge state boosted in an Electron Beam Ion Trap (EBIT), the ions are reaccelerated in a compact superconducting (SC) LINAC. For rare isotope operations, the LINAC is pre-tuned using stable pilot beams with a similar mass to charge ratio as the rare isotope beams and consequently the system is scaled. Scaling steps of up to 5\% are needed to change to the radioactive beams. To preserve the stringent beam characteristic on the experimental end station a precise online model is required. We will present the status of this online model.
