Radionuclear Beam Physics is at the forefront of international nuclear physics research. Breakthroughs in key scientific issues such as the new physics of drip line areas, celestial bodies with heavy elements above iron and nuclear synthesis of overweight and stable islands will have a significant impact on the entire natural sciences. These studies Both require high-intensity extreme abundance neutron beam. The beam of radionuclide produced by the target of advanced research reactor and intense deuterium ion accelerator is transmitted to the physical terminal. The simultaneous use of two charge-state beams accelerates the beam intensity effectively. By analyzing the synchronous acceleration principle of ion beam separation and injection, Adjusting the ion beam phase difference and the rate regulator synchronizing the ion beam energy, different types of nuclear beam extraction voltage parameters and rate synchronization parameters are calculated respectively. The relationship between the voltage regulation and the ion beam phase difference is analyzed and calculated, and the voltage regulation parameters are obtained. The calculation results show that when adjusting the voltage amplitude to ± 8 kV, different kinds of ion phase adjustment can be satisfied.
