| Abstract_FL | Background: The breakthroughs in researches on drip line of new physics and the process of celestial synthesis of heavy elements above iron and nuclide synthesis of super heavy island would have a significant impact on natural science, and in which high-intensity neutron rich beam plays an indispensable part.Purpose: The radioactive beam produced by China advanced research reactor (CARR) and the high intensity deuteron accelerator is transmitted to the physical terminal, and the beam intensity can be effectively enhanced by the simultaneous acceleration of the two-charge state beam.Methods: Based on the principles of scatter injection and synchronous acceleration for ion beam, the high voltage was used to adjust the phase difference of the ion beam, and the speed regulator to synchronize the ion beam energy, the extraction-voltage and rate-synchronization parameters of different kinds of ion beam are calculated, respectively. Voltage regulation parameters are obtained by analyzing the relationship between voltage regulation and phase difference of ion beam.Results: The results show that with regulate voltage at ±8 kV, phase adjustment for different types of ion beam can be satisfied.Conclusion: Physics design parameters can meet the requirement of engineering construction. |
