Heavy y Ion Linac Architecture<br />
EXAMPLE: the REX upgrade project at <strong>CERN</strong>-ISOLDE. Post-acceleration of<br />
radioactive ions with different A/q q up p to energy gy in the range g 2-10 MeV.<br />
An injector (source, charge breeder, RFQ) + a sequence of short (few gaps) standing<br />
wave accelerating structures at frequency 101-202 MHz, normal conducting at low<br />
energy (Interdigital, IH) and superconducting (Quarter Wave Resonators) at high<br />
energy gy → mix of NC-SC, , different structures, , different frequencies. q<br />
1.2MeV/u for all A/q<br />
