Description
This work reports a numerical investigation of the efficiency of an ECR-based charge breeder as a function of injected beam parameters. Combining particle-tracking with a realistic plasma-target model, simulations evaluate the effects of transverse emittance and longitudinal energy spread on the optimum injection conditions and the consequent breeding efficiency. The simulations use the modelled beam through the 1+ injection beam line installed at the LPSC test bench in Grenoble with variable energy spread and emittance as input, and then take into account electrostatic deceleration due to a realistic plasma potential profile, elastic Coulomb collisions and ionizations in a comprehensive description of the charge breeding process. The presented work supports optimization of ECR-based charge breeders for radioactive ion beam facilities and other applications requiring high charge-state production, by suggesting practical guidelines for on optimum 1+ beam manipulation.
